ATF fluid- This is a special gear oil that has a liquid consistency and has a mineral or synthetic base. It is intended for cars running on "automatic". ATF transmission fluid is responsible for performing many functions, for example:

• uninterrupted operation of the gearbox - its control and management;
• cooling and proper lubrication of parts that are susceptible to friction;
• transmission of torque, which passes through the torque converter from the motor to the box;
• ensuring the operation of friction discs.

Many people equate oil with an automatic transmission mixture, but the properties of ATF differ in many ways. To obtain the correct composition, mineral oils are used, to which special substances are added. If you use extraneous fluids for "automatics", then this will surely provoke a breakdown of the gearbox, or its complete failure.

The General Motors automobile concern became the manufacturer of the first oil specification. The new mixture entered the mass market in 1949. This was due to the fact that in 1938 the same company developed the first automatic transmission. Subsequently, the automaker came to grips with improving the specifications of transmission mixtures and established the strictest requirements for the composition. Since there were no competitors in this market, GM became the specification setter for the ATF.

The first varieties of liquid were made on fat, which was produced from the fat of sea whales. Due to the release of a law prohibiting the hunting of these inhabitants of the ocean, the corporation had to develop a synthetic base.

At the moment, competition from specifications from General Motors are other eminent car brands - Chrysler, Hyundai, Mitsubishi Ford and Toyota.

Pay special attention to the packaging of the purchased ATF fluid. Consider the type of oil as well as the specification that suits your gearbox.

Types of ATF gear oils

After we have become familiar with what ATF oil is, we will study all kinds of fluid specifications. The very first of them, as noted above, saw the light in 1949 thanks to the efforts of General Motors. The common name for the mixture is ATF-A, which was used on all vehicles equipped with "automatic". In 1957, the specification was revised and thus the Type A Suffix A was born.

So, there are such main types of ATF:

• Mercon- introduced by Ford in the 80s of the last century. They are as close as possible to other specifications and can be compatible with them. The main differences between the varieties from GM and Ford are that the former pays more attention to smooth shifting, and the latter to speed;
• Dexron- Produced by GM since 1968. Since whale oil was used in the manufacture, production had to be suspended. The reason for this was also weak technical characteristics, because the oil showed poor tolerance to high temperatures. In 1972, Dexron ІІС appeared, where jojoba oil served as the basis, which subsequently provoked corrosion of some parts. The next oil, which was equipped with additives that suppress the development of rust, acquired the prefix IID. Fluid with the IIE index was produced until 1993. Its distinguishing feature is the presence of additives that reduce hygroscopic excess. The output of the Dexron III type (1993) became innovative. The novelty retained its liquid properties even at very low temperatures, and frictional characteristics also improved. In 2005, a new generation appeared with the prefix "VI". An ATF transmission oil was developed for use on the new one, which was a 6-band. The mixture has a longer service life, as well as a reduced degree of kinematic viscosity. The last parameter allows you to increase fuel efficiency;
• Alison C-4- developed by General Motors specifically for pouring into large vehicles - off-road vehicles and trucks.

When to change the transmission mixture?

ATF fluid needs to be changed periodically, because this will increase the service life of not only the transmission, but also the car as a whole. Therefore, it is necessary to carry out systematic measurements of the oil level. The replacement period is affected by:

• vehicle mileage;
• terms of Use;
• driving style.

The procedure should be entrusted to specialists at the service station, where there is all the necessary equipment that will allow you to change the oil. After all, you can only drain part of the ATF fluid on your own, a significant part remains in the box. With the help of technical devices, professionals will also be able to wash or replace the filter.

Checking transmission oil in automatic transmission

The long service life of the transmission is ensured by the timely check of the balance of the mixture in the automatic transmission. This operation is carried out in different ways - it all depends on the type of transmission. Before proceeding with the procedure, carefully read the user manual.

You can check the remaining mixture level both on a hot and cold transmission, because the dipstick has the corresponding marks.

If you decide to carry out this operation yourself, then you should remember the need to observe the exact oil level. In each case, you expose the entire system to danger:

• an insufficient level provokes air to enter the pump along with the oil (in this situation, burning occurs, friction slips and a general failure of the system). If you find that the level does not reach the desired mark, then try to determine the cause of the oil leak;
• an increased level causes excess oil to overflow through the breather, the level decreases, therefore, the same problems arise as in the above situation. Emission through the breather is diagnosed by the degree of contamination of the part with liquid.

How to choose a working fluid according to the ATF specification

Each of the groups of oils has different friction characteristics and differences in temperatures. What do the different ATF specifications mean:

• Dexron II does not tolerate too cold temperatures, therefore, it is suitable for use only in those countries where the temperature does not fall below -15 degrees during the winter season. Suitable for cars of previous generations;
• Dexron II it performs well even at temperatures as low as -30, it is necessary only in those areas where severe and frequent frosts prevail. The manufacturer guarantees that the liquid will retain its viscosity. Even if your transmission uses IID, change it to IIE in cold weather;
• Dexron III It is used literally on all modern car models.

An incorrectly selected mixture will provoke multiple malfunctions in the functioning of the automatic transmission. Very predictable slippage of discs, an increase in the time it takes to change gear, the occurrence of jerks at start-up and. All this will be caused by a longer formation of the working oil pressure. Initially, you may not pay attention to such symptoms, but then they will manifest themselves to a greater extent.

Can liquids of different types be mixed?

Mixing liquids is acceptable, but it’s still better not to risk it, because it can lead to breakdown, and a complete replacement of the automatic transmission will hit your pocket pretty hard. In order to identify the type of oil, add a special dye to it, which will not affect the characteristics of ATF oils. If it is not possible to determine the specification, then it is better to completely reload it.

Long-term use of the same fluid, or the use of a low-quality fake, leads to malfunctions and breakdowns in various engine systems.

ATF operation issues

Transmission longevity depends on maintaining optimum fluid levels. If you know what ATF is, then you also know that oil changes are carried out only in car services under the supervision of specialists.

The fact that something is wrong with the liquid is indicated by its black or dark brown color. At the same time, a burning smell is observed. The color of a normally functioning transmission oil is deep red or red with an orange tinge.

As noted above, it is important to prevent fluid transfusion. Foaming of the oil provokes its release through the breather. If the level is insufficient, then the pump captures air. This affects the clutches - the discs begin to slip and burn out.

All power steering fluids differ from each other, not only in color, but also in their characteristics: oil composition, density, ductility, mechanical properties and other hydraulic indicators.

Therefore, if you are worried about the long and stable operation of the hydraulic power steering of a car, you need to follow the operating rules, change the fluid in the power steering in time and fill in the best quality fluid there. For the operation of the power steering pump use two types of fluids- mineral or synthetic, in combination with additives that play a major role in the operation of the hydraulic booster.

It is quite difficult to determine the best fluid for power steering, because, according to the manufacturer's recommendation, it is better to pour the prescribed brand into a particular car. And since far from all drivers comply with this requirement, we will try to compile a list of the 15 best power steering fluids that caused the most confidence and collected a lot of positive feedback.

Notice that such liquids are poured into the power steering:

• conventional ATF, as in an automatic transmission;
• Dexron (II - VI), the same as ATP liquid, only a different set of additives;
• PSF (I-IV);
• MultiHF.

Therefore, the TOP of the best power steering fluids will consist of similar categories, respectively.

We present a revised version of our material on the interchangeability of different types of ATF. It takes into account the changes in the world of transmissions and oils in recent years, changes in logistics and prosperity ... Let's start with a direct answer to the question in the title, and then go through the main Toyota transmission fluids.

Working fluid specification for domestic market models from the 1980s (A13#, A24#, A54#, A4#, A34#, A44# series machines, etc.). In foreign markets, these models were ordered to be fueled with Dexron II/III type ATF without mentioning D-II.

There is no technical sense in acquiring this particular liquid. Any ATF meeting Dexron II/III specifications should be used.

This Toyota liquid is not in the repair or operating manuals, since it appeared much later than the end of the production of models with classic automatic machines. Supplied in all markets as an original replacement for the obsolete ATF D-II.

There is no technical point in purchasing this particular fluid, but under specific conditions, D-III may be more affordable and cost-effective than branded ATFs.

It was used from 1988 to 2002 in the A241H and A540H "all-wheel drive" automatic transmissions for better operation of the partial locking center differential clutch.

The original is still supplied to the domestic market. In the foreign market, Type T-IV is semi-officially considered a replacement for Type T, however, the T-IV canister directly states - "not recommended for use in machines for Dexron 2/3 or Type T".

Many years of local practice has shown that cars with these automatics work perfectly on conventional Dexron type ATFs without any deterioration in the functioning of the four-wheel drive.

The offer on the market for Type T is small, and there is no point in purposeful acquisition. Use as a substitute for Type T-IV can damage fairly old transmissions, so it is best to use less aggressive Dexron II or III specification fluids.

ATF Type T II
Used in 1990-1997. for some automatic machines with electronic control (A34# series on classic sedans). Officially replaced by T-IV.
In practice, it has been successfully replaced by any traditional ATF. Today, the use of Type T-IV as a substitute can damage fairly old boxes, so it is best to use less aggressive fluids according to the Dexron II or III specification.

ATF Type T III
Used in 1994-1998. on some machines with Flex-LockUp (part A34#, A35#, A541E, A245E). Officially replaced by T-IV.

Basic specification for all Aisin boxes after 1997 (U44#, U34#, U24#, U14#, early U15#, A65#, late A24#E, A34#).

At the very beginning of the 2000s, traditional ATFs such as Dexron III were successfully used instead of the then rare and expensive T-IV. Later, independent oil manufacturers launched the production of ATF specification 3309 and universal ATFs, and later the supply of the original T-IV grew so much that it became perhaps the most affordable liquid of its specification - it is often purchased by owners of other car brands with similar Aisin (Audi, Chevrolet, Daewoo, Fiat, Ford, Mazda, Opel, Porsche, PSA, Renault, Saab, Suzuki, VW, Volvo etc).

Using the Dexron specification instead of T-IV ATF does not entail negative consequences, but today it is no longer practical.
It is equally correct to use both the original Type T-IV fluid and any ATF that meets the JWS 3309 specification - depending on the specific circumstances.

Valid since 2004, the main specification used in modern 5/6/8-speed automatics (series U15#, U66#, U76#, A75#, A76#, A96#, AA8#, AB6#). Differs in significantly lower viscosity in comparison with the previous ATF T-IV.

Liquid in sufficient quantity is presented on the market. It is equally valid to use either the original WS or any ATF conforming to the JWS 3324 specification, depending on the specific circumstances.

Together with the first Toyota CVTs in 2000, a specialized working fluid for CVTs appeared.

It is optimal to use the original CVTF TC, which is presented in sufficient quantities on the market. Any fluid that meets the JWS 3320 specification can be used. General purpose CVTFs can be used if the need arises.

Since 2012, a gradual transition of all CVTs to the new "energy-saving" FE fluid has begun - with a noticeably lower viscosity and fewer useful additives.

It is optimal to use the original CVTF FE, which is presented in sufficient quantities on the market. In case of urgent need, it is possible to use universal CVTF.

"Why write about it? Today everyone can afford the original"
Let now there are no problems either with the availability or with the price of the original working fluids. But the question is different - perfectly reasonable advice "Must use recommended fluids" too often replaced by the slogan "You can not use anything other than the original!" It is impossible to put up with this rough manipulation, once thrown by cunning dealers in Japanese spare parts, picked up by officials and smashed by a mass of owners far from technology.

"Oil or ATF - scholasticism?"
In manual transmissions, the transmission butter almost exclusively serves as a lubricant. In an automatic transmission, the main task liquids- power transmission from the engine to the box, then work in the hydraulic control system, providing the necessary friction in the clutches, cooling the rubbing elements and lubrication itself. Therefore, the broader concept of ATF (Automatic Transmission Fluid) has been established - automatic transmission fluid.

"Why are GM and Dexron taken as a starting point?"
Today, the GM-Ford joint venture for the production of automatic transmissions is on the sidelines of life and deep in the shadow of the world's transmission giants - Aisin, ZF, HPT, Jatco ... Nevertheless, it was GM who were the founders of the mass use of automatic transmissions, the world's largest OEM suppliers of automatic transmissions, and their fluid specification for many years became synonymous with the very concept of ATF.

A bit of spec history from GM:

1949	ATF Type A - GM's first ATF specification
1957	ATF Type A suffix A - specification update
1967	Dexron B - the first specification with the Dexron designation proper
1972	Dexron IIC - variant with new friction modifiers
1975	Dexron IID - a revised version of IIC that has become the most common standard and synonymous with ATF for many years
1991	Dexron IIE - improved specification with better viscosity-temperature properties
1993	Dexron IIIF - unified replacement for IID and IIE
1997	Dexron IIIG - new requirements for frictional and antioxidant properties with IIE viscosity characteristics
2003	Dexron IIIH - advanced base with better durability, protection against oxidation and foaming
2005	Dexron VI - a new, noticeably less viscous fluid

- Specifications "Dexron IV" and "Dexron V" officially did not exist, although in slang it could be called IIIG and IIIH. The marketing designation "D-IV" for late dexrons was sometimes used by independent oil producers on the market.
- Shortly after the release of the D-VI, GM canceled all previous specifications and declared the new ATF to be fully backward compatible with all early Dexron types. In reality, the transfer of old boxes to a liquid of a different composition and with noticeably different viscosity characteristics looks extremely doubtful.
- The original GM Dexron VI was notorious for its tendency to darken very quickly (to the point of engine exhaustion), although the manufacturer officially considers this behavior to be the norm.

"Universal Fluids?"
Here is a clear example of how the manufacturer of "Toyota" transmissions - Aisin - refers to the idea of ​​​​a narrow specialization of fluids: AFW + - an alternative everyone ATF from D-II to WS (as well as a lot of original ATFs from other brands), CFEx is an alternative to all CVTFs, including TC and FE.

Today it is becoming a trend: one liquid - for all automatic machines, another liquid - for all CVTs, absolute backward compatibility with early ATFs.
Of course, we strongly welcome such official confirmation of our words more than a decade ago about the interchangeability of ATF. But let's try not to forget one more important principle - "do not interfere with the car to work" - for properly functioning boxes of 10-15-25 years of age, it is best to continue using the fluid that they have been driving so far.

"Periodicity?"
It would be appropriate to recall not only "what", but also "when" to pour into the automatic transmission. However, since the beginning of the mass operation of machines, the answer has not changed: every 30-40 t.km it is worth at least a partial replacement (updating) of the liquid, every 80-120 t.km - a replacement with the removal and cleaning of the pan, magnets, mandatory filter replacement. It’s even better not just to “renew” the liquid, but to change it by displacement (with a stand cooler connected through the hoses, through which, when the engine is running, fresh liquid is supplied and the old liquid is drained - this is how the box lines and the torque converter housing are washed).
In the 2000s, many new machines lost control probes, and the frequency of mandatory ATF replacement disappeared from the instructions (but the concept of "working fluid is designed for the entire service life" arose). Officially, it is proposed to check the condition of the fluid every 40 t.km, and change it after 80 t.km only under especially difficult operating conditions. Literally following such recommendations will sentence an automatic machine, especially a modern one, already in the second hundred thousand kilometers, therefore, for long and trouble-free operation, it is better to adhere to the traditional ATF replacement frequency, even on the newest cars.

"What did the manufacturer recommend to fill in my box (A541E, A340H, A245E)?"
The exact recommendations of the manufacturer can be called, knowing not only the model of the box, but also the model and year of manufacture of a particular car. Firstly, the same Toyota designations were worn by several assault rifles of slightly different designs. Secondly, the recommendations changed periodically even during the release of one generation of the model (this happened especially often during the appearance of the next, new at that time specifications - T-IV, WS, FE).

"What is flex lock-up?"
Starting in the mid-1990s, Aisin automatic transmissions introduced a "partial lock-up" (FLU - Flex Lock Up) torque converter operation mode. Previously, automatic torque converters operated in two modes - either with torque transmission from the engine only through liquid, or in full lock mode, when the crankshaft, transformer housing and box input shaft are tightly connected by a friction clutch and the torque is transmitted purely mechanically like a traditional clutch. In a box with partial blocking, there is an intermediate mode in which the clutch can slip to one degree or another during the transmission of force. At first, partial blocking was used at light loads and in a rather narrow speed range, but in order to increase efficiency and improve dynamics, full and partial blocking modes on more modern machines began to be used more and more often.
Of course, FLU is not a Japanese know-how, so since the development of the Dexron III specification, the requirements for automatic machines with partial blocking have been taken into account.

"They say if you fill in Dexron instead of T-IV, then there will be shocks?"
When filling any fresh liquid, even the original one, some changes in the behavior of the machine are possible, and not always positive. Fresh ATF always differs from the old one in its chemical / physical properties (even more than two different types of fresh liquid differ from each other), and in its own way affects the operation of the box, which has already "adapted" to the old ATF.
In our practice, no differences in the behavior of serviceable machines when using other ATFs instead of T-IV (even without approval 3309) were noted.

"Where can I find out the viscosity of the original fluid?"
Safety data sheets for all original materials, from paints and oils to antifreezes and fragrances, have been on the main Toyota website for a long time and are regularly updated.

"What is the code for the most correct original Type T-IV?"
The original Toyota ATF can take a variety of external forms: a metal "Japanese" can (black, white, gray), a black plastic "US" bottle, a gray plastic "European" canister ... you should not try to distinguish the "more real" from them.
And that's why the retail price of the original ATF in the Russian Federation sometimes turns out to be one and a half to two times lower than in Japan or the USA ... it's better if it remains a little trade secret.

"Type T can be officially replaced by Type T-IV"
On the one hand, in June "98 Toyota issued service bulletin TC003-98 for the American market, according to which the then-new ATF Type T-IV completely replaced the previous T-II and T-III, but did not replace the Type T itself.

On the other hand, in the technical documentation for the domestic market, substitutes for Type T have never been provided, and on the original metal canisters with Type T-IV it is still indicated in Japanese and in English "not recommended to use... instead of Type T".

Which option is more correct? The first and last of the models with a Type T transmission that was distributed on the foreign market was the RAV4 SXA10 (for which these bulletins appeared), however, almost two dozen models were produced in Japan in 1988-2002, moreover, much more massive, with boxes A241H and A540H. Therefore, in matters of operation of all-wheel drive, the practices of the domestic market deserve more trust. And today you can add - if the Japanese Toyota officially recognized the Type T replacement, it would not have traded this fluid in the late 2010s, but immediately sent it into oblivion as T-II, T-III and dozens of other oils of really outdated specifications.

"And in fact, did anyone fill in non-original liquid?"
I would like to remind you that Japanese cars appeared in the country back in those days when there were no mobile phones, the Internet, and in Primorye they drove along the winter road ... And, of course, there was not even the very concept of "original liquids", the commodity import of which only began at the turn of the 2000s. But from the very beginning of the 1990s, tens of thousands of Toyotas (including those with A241H, A540H, A245E, A340E boxes) have been operated here on any available ATF - without breakdowns or problems, and many of them still feel good today.
But before buying a completely non-branded ATF, we strongly recommend that you familiarize yourself with the final part of our articles on the choice of engine oil.

"Everything is clear... but maybe the original is still better?"
Of course, because in addition to the benefits for the car, the use of original working fluids has a calming effect on the owner and increases his heart rate. And do not forget that in addition to the original ATF, the instructions prescribe to use:
only Toyota approved engine oil
only original coolant "Toyota genuine Super Long Life Coolant"
only original power steering fluid "Toyota genuine Power Steering Fluid"
only original brake fluid "Toyota genuine Brake Fluid 2500H"
only original compressor oil "ND-Oil8-11"...
As well as only genuine Toyota parts.
Purchased only from authorized Toyota dealers.
Otherwise, the car will immediately fall apart, right?

With the advent of modern automatic transmissions, the issue of protecting mechanisms and assemblies has become acute. Oils for manual transmissions were unsuitable because their characteristics did not meet the necessary requirements. An automatic transmission, like a mechanic, shifts gears, but the machine operates independently, and this greatly complicates its design. In addition, the operating conditions of the mechanisms and components of the machine do not correspond to the operating conditions of the mechanics, so a new ATF type of lubricant was developed for it.

Lubricant ATF

ATF fluids are special oils used to work in automatic transmissions with a hydraulic transformer, as well as in some models of variators. The abbreviation for lubricants is deciphered as follows: ATF (Automatic Transmission Fluid, automatic transmission fluid). The purpose of the lubricant is to protect the internal parts of the box from corrosion, overheating and wear, in addition, with the help of a liquid, an impulse is transmitted from the transmission power plant. Lubricants are liquid, with increased fluidity, mineral or synthetic base.

The transmission fluid performs the following functions:

1. Control and management of automatic transmission;
2. Cooling of parts and mechanisms;
3. Formation of a protective film on the surface of parts;
4. Corrosion protection;
5. Prevention of early wear of mechanisms due to friction forces;
6. Transfer of impulse from the power plant to the transmission;
7. Helps to work friction discs.

Working fluid in mechanical boxes and ATF automatic transmission oil, lubricants that are not similar to each other. ATF fluid performance differs from conventional oil in many ways. To create the desired consistency, mineral oils are used, adding special additives to them. Each automatic transmission is suitable for a certain type of oil, with its inherent set of characteristics. The use of an inappropriate liquid inevitably leads to a breakdown of the mechanism, which is why it is so difficult to find a product similar to the original.

For the first time, the specification for gear lubricants was put into use in 1949. The concern that offered to do this, General Motors, had no competitors and analogues at that time, and ATP fluid was specially developed for the automatic transmission designed by the company. At present, the development and standardization of transmission fluids are carried out by: Hyundai, Toyota, Ford, Mitsubishi, GM.

Types of ATF fluids

The first type of ATF in automatic transmissions was produced by GM, it was called ATF-A. In 1957, a modernization was made and a new fluid appeared under the name Type A Suffix A.

Types of ATF fluids on the market today:

• The Mercon type, developed in 1980, was carried out by automaker Ford. Compatible with other types of lubricants as their characteristics are identical. The difference from competitors is the calculation for the use of fluids in mechanisms where speed is needed when shifting gears.
• Starting in 1968, GM began producing a lubricant called Dexron. The liquid did not tolerate high temperatures, in addition, it was based on whale fat, so production was soon stopped. Since 1972 the type has been replaced with a new fluid called Dexron IIC, however the product was prone to corrode in some parts of the box so it was also replaced with Dexron IID which used anti-corrosion additives. Until 1993, GM produced oil with the prefix IIE, which was famous for its ability to minimize the amount of moisture in the box. GM gained fame with the release of Dexron III fluid in 1993. The product had increased fluidity and performance at low temperatures, as well as improved properties in relation to rubbing surfaces. It is applied to hydraulic boosters and hydraulic systems. In 2005, a new liquid with index IV was released. The product was developed for a six-speed gearbox, has improved performance, extended service life, improved fuel efficiency.
• Alison C-4 grease, used on trucks and construction vehicles.

Especially for automatic transmissions of Toyota and Lexus cars, Toyota has developed ATF WS fluid. It is successfully used in automatic transmissions and automatic transmissions with the possibility of manual shifting. ATF WS Toyota grease is a priority when it comes to its use on cars manufactured by the company.

ATF fluid replacement

Transmission fluid refers to consumables that change periodically. Timely replacement of ATP in automatic transmission increases the service life of transmission parts and mechanisms, because in the process they are subject to increased wear, the products of which settle in the oil.

Conditions affecting the oil change interval:

• Intermediate vehicle mileage between fluid changes;
• The environment and conditions in which the car was operated;
• The nature of operation and driving style of the vehicle.

The design of automatic boxes requires the mandatory removal of the pallet and cleaning the magnets from metal chips and accumulated debris. When changing the oil, the filter element must also be changed to remove impurities and ensure the purification of the liquid in the future.

It is advisable to carry out the procedure at branded service stations equipped with special devices for pumping out residual liquid from the system. Independent operation will allow only a partial replacement of the fluid, which may adversely affect the operation of the unit in the future.

Checking the ATF level in the box

The quality of the performance of functions and the duration of the life of the box directly depend on the level of lubricating fluid in the product. The procedure for checking the oil level is carried out regularly, since the deviation of the established norms entails unpleasant consequences:

• The lack of oil leads to the ingress of air bubbles picked up by the pump, and the rapid wear of the clutches in the future. They also burn, which disables the system.
• An excess of lubricant leads to its leakage through the ventilation valve, which is fraught with the loss of a significant amount of fluid and also the failure of the clutches.

Liquid level control on each box model is carried out in accordance with the requirements. Before performing work, it is necessary to familiarize yourself with the documentation for the product and follow the procedure clearly following the established regulations.

Fluid selection according to ATF specification

• Dexron B: the first specification for ATF fluids, developed in 1967;
• Dexron II: development begins 1973, the standard has received worldwide recognition;
• Dexron IID: beginning of implementation in 1981, designed for automatic transmissions operating at temperatures not lower than -15°C;
• Dexron IIE: launched in 1991, designed for automatic transmissions operating at temperatures down to -30°C. Synthetic base, improved viscosity characteristics;
• Dexron III: Introduced in 1993, designed for use in modern gearboxes, increased requirements for viscosity and friction;
• Dexron IV: Synthetic, packaged in modern boxes.

Ford also has a specification, its name is "Mercon", but the marking has not been widely used, it is unified with the GM specification. For example: DesxronIII / MerconV.

Crysler also specifies its products, the specification is called "Mopar". In our region, it is not common, and if it occurs, it is also unified with Dexron.

Mitsubishi (MMC)-Hyundai classification:

• Type T (TT): used in A241H and A540H all-wheel drive boxes manufactured in the 80s;
• Type T-II: designed for electronically controlled automatic transmissions produced in the early 1990s;
• Type TT-II: electronically controlled automatic transmissions from 95-98;
• Type TT-III: electronically controlled automatic transmissions from 98-2000;
• Type TT-VI: electronically controlled automatic transmissions after 2000;
• ATF WS: A generation of synthetic lubricants used in modern transmissions manufactured by Toyota.

Incorrect selection of the mixture entails a large number of breakdowns, so you must refer to the documentation for the product and follow the recommendations that are written there.

Interchangeability of ATF fluids

Important! Toyota ATF WS is not interchangeable with Toyota and Dexron fluids. WS grease has the ability to absorb moisture, so the storage container is opened once.

If necessary, ATF WS gear lubricant is replaced with third-party oils of similar characteristics: Idemitsu, Aisin, Zic.

When changing the lubricant in an automatic transmission, it must be remembered that modern transmission fluids are a mixture of components in a certain proportion, each of which individually represents the final product. The settings of modern automatic transmissions after 2003 are sensitive to the change of components and take into account their specifics in the process of work. Thus, if there is doubt about the type of old oil, it is necessary to do a complete replacement.

What is ATF SP3? Today, only a beginner does not know that a suitable gear oil is necessary for a car engine. In this case, the engine of the car will not deteriorate ahead of time. So, owners of Mitsubishi, Hyundai and Kia will need the appropriate lubricant. ATF SP3 is considered a good option. This lubricant will ensure that the automatic transmission runs smoothly. The automaker recommends that car owners use SP3. There are some points of contention, but the vehicle manufacturer knows best which oil is preferred for his product.

For Mitsubishi, Hyundai and Kia vehicles, it is best to use ATF SP3 gear oil.

Description of transmission oil ATF SP3

ATF oil does not look like similar products even at first glance. Grease is colored red. The product is based on high quality components. It's made in the USA. Oil production is carried out in accordance with current international quality standards. Lubricant can be used in any weather, as it is all-weather.

ATF fluid works great in hot and cold weather. It is convenient to use such a lubricant: there is no need to change the oil when winter comes or, conversely, summer.

Metal parts in units and assemblies function well. The car drives smoothly and silently. This grease is not recommended for use in manual transmissions.

Gear oil has many advantages:

• excellent frost resistance: the liquid begins to freeze only at a temperature of -40 ° C;
• high fluidity;
• good pumpability;
• corrosion protection;
• resistance to oxidation;
• no foaming.

Other products of a similar purpose will not be able to achieve such high values ​​​​of the operational properties of automatic transmissions. Only with these oils can your machine run at peak efficiency.

In addition, automatic transmission parts will not break, and the formulas used by the manufacturer help to save oil. The product is sold in packs of 0.95 liters. Buy lubricants in trusted places so as not to get a cheap fake. Store the liquid canister in a dark place so that the rays of the sun do not fall. There are appropriate inscriptions on the label of the original product. When choosing this product, the consumer takes care of his "iron horse" and saves his money to a large extent. Now there is no need for a major overhaul of the transmission, and there is no need to frequently change the oil for the gearbox of the vehicle.

Lubricant indicators

The automatic transmission works great if only the oil recommended by the manufacturer is used. The driver should familiarize himself with all the requirements that are contained in the car's operating manual.

The performance of a fully synthetic ATF SP III fluid is as follows:

• stability - corrosion, thermal, oxidative;
• excellent extreme pressure properties;
• good viscosity-temperature characteristics;
• excellent shear stability;
• ensuring smooth gear shifting;
• good compatibility with any type of seals or elastomers;
• excellent anti-friction performance;
• excellent thermal conductivity.

After the creation of original oils, finished products are subjected to rigorous tests in order to find out how well the products correspond to the declared characteristics. The liquid that goes on sale and is sold on the market must necessarily comply with international quality standards and the requirements of Mitsubishi itself.

Motor oil lines are recognized as corresponding to the following quality classes:

• API SM;
• ILSAC GF-4.

The manufacturer creates packages of additives for modern oils. They allow you to provide high performance during engine operation and increase the working life of the engine.

Motor oils produced for Mitsubishi cars have a distinctive characteristic. The lubricant is energy-saving, low viscosity. The manufacturer has made it his first task to reduce fuel consumption. However, high performance properties are maintained at operating temperatures.

This quality of oil is acquired through the use of modern high-quality components in their composition. They have a high viscosity index. The viscosity of the lubricant practically does not change throughout the entire period of operation, regardless of the value of the operating temperature at low viscosity products. Purchase original lubricants if you want to protect the "iron horse" from wear and leakage. If you want to change the oil, the car owner must drain the fluid that he uses and fill in a new one. When there is no experience, it is better to contact a car service. If the owner of the car has been driving for more than a year, he can independently replace the transmission fluid.

How are lubricants changed at Mitsubishi?

To change the oil, the vehicle must be parked on a level surface.

1. Park your car on level ground. It is advisable to choose a hard coating for this purpose. Put the car on the parking brake. To have access to the car, use a jack or put the car on a viewing hole or overpass.
2. Wipe the top of the crankcase thoroughly.
3. Loosen the bolt to remove the retaining plate and remove the speedometer drive assembly. Check the condition of the assembly sealing ring. If there is damage, it will need to be replaced.
4. Wipe the surface of the crankcase base near the drain plug. Place a container under the drain hole that will serve as a receiving container. After that, carefully remove the cork.
5. Wait until the oil flows into the drain container. If the engine has been warmed up, then take all precautions so as not to burn your hands. Wipe off the drain plug. It is necessary to remove small metal filings from the magnetic insert. Prepare a new washer.
6. When the oil stops flowing into the drain container, clean the threads at the drain plug and crankcase opening. Install a new sealing washer. Screw the plug well, tightening it at the end.
7. Pour transmission oil into the crankcase opening. Control the amount of liquid poured. It should not exceed the amount specified by the manufacturer. Check the oil level in the car. Correct if necessary. Add liquid or pump out excess. Reinstall the speedometer drive assembly. Drive the machine for a short drive, during which fresh oil will be distributed to the transmission components. Check the oil level again.

Unforeseen situations happen along the way. If you are on the road, and the oil level has dropped to critical, then you need to add lubricant.

An experienced driver always carries a can of oil with him.

And what to do when there is no additional lubrication in the car? You can stop near the auto shop and buy the right lubricant. When ATF SP3 is not available, get ATF 3309.

This high performance fluid is used in automatic transmissions. It is recommended for use in Mitsubishi. Lubrication will provide excellent lubricity, quiet operation, vibration reduction, excellent vehicle handling and smooth gear shifting.

Part wear is reduced and transmission life is extended.
