Where else is used transmission oil. Transmission oil is poured. Composition and chemical properties

Good day, dear car enthusiasts! Replacing the oil in the gearbox, the question is serious and responsible. We always have two options for you: either to replace the oil in the box with your own hands, or contact your service service.

Oil replacement technology in a manual transmission or transmission fluid in an automatic transmission is not special "wisdom". You just need to know. And if you have half an hour of free time, oil in the gearbox and desire, then replace the oil yourself.

What needs to be done to extend the life of the gearbox?

Like any mechanism in which in intensive mode, driving parts, a mechanical and automatic transmission are operated equally require attention and timely maintenance. Especially in terms of lubricating material.

How can I extend the service life of the gearbox

  • if you do not have a tuning car, but an ordinary standard instance, then the operation of the machine must occur in standard mode. Smooth overclocking, regular braking, economical (cruising) high-speed mode within 100-120 km / h. - this will default increase the life of the gearbox;
  • : in a manual transmission - smooth with a spinning clutch gear shift, in an automatic transmission - execution of the selector switching rules;
  • check how much oil in the gearbox every 10,000 km, in spite of sometimes sounding opinions about the fact that the gearbox is not required in the checkpoint. Traditionally, in the manual transmission, the oil level should be on the lower edge of the oil-coaling neck, in the automatic transmission according to the indicator on the probe. The volume of oil or transmission fluid must be specified in the manual for each CAT model individually;
  • pour oil into a manual transmission, and oil in an automatic transmission, only recommended by the manufacturer, or its analogues. Yes, by the way, do not forget that non-oil is poured into the automatic transmission, but a special transmission fluid with ATF abbreviation (Automatic Transmission Fluid)
  • observe the period of replacement of oil in the gearbox, which, as a rule, are indicated in the manuals of your car models. If there are no numbers, it is recommended to change the oil in the gearbox: MCPP is 100,000 km. Run or once every seven years old, automatic transmission - 90000 km. Run or every six years. Depending on what comes before.
  • systematically monitor whether the oil stain, or drops of oil appeared under your car. This is a signal to the need for serious diagnostics of the PPC.

How to replace oil in a manual transmission?

We need an elevator, although from where it is in the garage. Then the repair (observation) pit or estacade. Standard set of tools, tanks for draining waste oil and syringe, because From the standard container, the transmission oil will not be pouring.

All this is, then proceed:

  • before making a car to replace oil in the checkpoint, you need to make a small "march-throw", about 10-20 km so that the oil is warmed up and has fluid. After the trip, the oil replacement must be started for 10-15 minutes;
  • install the car on the pit;
  • unscrew the oil tape plug in order to facilitate oil drain, by the way, immediately check the state of the sealing ring on the lid. If necessary, replace it;
  • turn away the plug of the drain hole and drain the oil into the container;
  • watch the drain hole;
  • syringe pour oil into the oil-teller hole to the level of its lower edge;
  • watch the plug of the oil-free hole. Here, perhaps, that's all.

How to replace oil in an automatic transmission?

When replacing the transmission fluid in, initial actions and tools, the same as when replacing oil in the checkpoint. After installing the car on the pit:

  • disconnect the supply hose from the cooling radiator fitting of the transmission fluid automatic transmission.
  • the hose is lowered into a pre-prepared capacity of at least 5 liters;
  • we start the engine with the lever of the selector "N" and drain the working fluid. The engine during plum may not work more than one minute. Otherwise, the transmission pump can fail;
  • "Wilder" engine;
  • turn out the plug of the drain hole and drain the remaining transmission fluid out of the box;
  • watch the plug hole, the syringe fill the fresh working fluid into the bulk hole at the top of the crankcase box. Fill 5.5 liters. After preping the fluid level pointer;
  • then, with a syringe, through the liner hose, pour 2 liters of liquid;
  • we run the engine, and drain through the hose 3.5 liter of fluid;
  • "Wasting" engine and fill over a 3.5 liter hose;
  • the last two operations continue until the fluid flows out from the hose in the volume of 8 liters;
  • then pour the working fluid into the box in the volume indicated by the manufacturer.

Important! Do not pour the transmission fluid "about the supply". In the automatic transmission must be flooded with so much working fluid as indicated in the manual for maintenance. No more, no less.

After that, check the level of the transmission fluid. On the level indicator there is a label. Then make a small trip, and again check the fluid level. Accordingly, the liquid must be in terms of the level. If necessary, a fraction.

Good luck to you when replacing oil in the gearbox with your own hands.

Replacing the automotive oil - the main lubricant that does not give metal components coming into contact with each other, come into disrepair, a very important procedure. The article will talk about oil for the gearbox.

ROLE OF OIL IN CAT

We will understand to start, why it is necessary so oil for the box. Look inside the detail.

The fact that in the gearbox there are gears installed on the shafts that, in turn, rotate on the bearings and the fact that the gears come into contact with each other by teeth - all this we know.

Forget that high pressure and considerable longitudinal slip is negatively affected by, destroys the oil film in the contact zone of rubbing parts, leads to the metal and in the end, everything is destroyed.

Important properties

Eliminate the negative effects of the environment and the inevitable processes of mechanics are designed viscous oil with special additives. It is able to ensure the safety and small susceptibility of the oil film to different influences. It will also be useful to know that even at the stage of production of gears and other box parts, those are covered with phosphate.

As for the additives, the transmission fluids for boxes contain the same substances that are in motor lubricants. We are talking about anti-wear, viscous-temperature, anticorrosive and other additives. Only here in the transmission fluid these most additives are mixed in other proportions.

In addition, to reinforce the oil film, make it stronger, chlorine, zinc, sulfur and phosphorus compounds are added to the liquid - in one word, a whole bouquet of Mendeleev's table. But there are durable oxide films, perfectly opposing high pressure and mechanical effects.

Types of oils

Like the engine oil, the transmission fluid has three varieties or type of bases. Synthetic, semi-synthetic and mineral base. Consider each of the foundations separately, we learn their appointment and role.

Synthetic base

  • She is it has better fluidity Compared to mineral. On the other hand, with extreme changes in operating temperatures, such oils can cause unwanted leaks through the gearboxes of the gearbox. Especially relevant such a situation with a car with a large mileage;
  • There are synthetic oils and advantages in addition to better yield. So, the thickness of the synthetic oil is less dependent on the decrease in temperature in cold seasonthat allows them to be used in a wider temperature range, making from them all-season;

Semi-synthetic base

  • Is a kind of hybrid, a combined option, something average between the total "synthetics" and "mineralical";
  • This oil is designed to ensure the improvement of the properties of mineral oils, while reducing at the same time high cost synthetic.

Mineral base

  • Consider the most consumed, so to speak, popular oils, due to their cheapness;
  • In order to somehow improve the quality, a certain number of additives with a large sulfur content is added there.

It turns out that synthetic oils in their quality is better than mineral, but at a price much more expensive. The semi-synthetic is somewhere in the middle, giving the opportunity to save.

Important: Remember that in no case cannot mix "synthetics" with mineral base or vice versa!

Difference oil by type of box

In addition, oils must be able to distinguish them by their properties. To date, two types of oils are known: for and for. That is what their differences.

For transmission

  • Oils for manual transmission (or MTF) effectively remove mechanical loads, the friction pairs are lubricated, heat and rust particles are removed.

It should be known that all gears and bearing inside them require lubrication with immersion in oil and splashing. In some structures (especially loaded or complex mechanisms) and such a lubricant is not enough. Oil in such cases ensures a forced pressure under pressure.

For automatic transmission

  • Difference (they are marked as ATF.) is that they are applicable higher demandsthan to lubricant for manual transmission. This oil performs the role of the mechanical energy transmitter in the entire transmission system. Rather, it is a hydraulic fluid than ordinary oil;
  • These oils are not only able to lubricate gears, but also provide a liquid medium, as well as smooth operation of frictional mechanisms, it is better to get warm and protected from corrosion;
  • They have more high viscosity index and better resist foaming;
  • ATF lubricant is weaker to affect the glands and various elastomers than oil for the manual transmission;
  • Such oils should be very racks and to oxidation.

Often on the forums ask such a question: Is it possible to use the oil for the machine in the mechanical boxes. In conventional MCPP, it is impossible to fill this oil, as it is a dense of it below, and there are no necessary antifriction additives. But, there are some MCPP models in which, in addition to conventional transmission oil, the ATF (Automatic Transmission Fluid) is also provided by the manufacturer. For example, such gearboxes were installed on some old Mercedes models. If we say in general - do not do it.

Classification of oil by viscosity

The basis figured out, now we turn to one of the most important characteristics - the peculiarities of a particular oil and classification according to the degree of viscosity SAE and API..

API classification implies the separation of all known transmission oils on 7 groupsThe most common of which are GL-4. (moderate loads) and GL-5. (Hard, extreme loads).

Classification (detail about this classification can be read in other articles of our site) conditionally divides oil on 3 groups: Winter / Summer / Vise.

Below we see the table in which the most popular transmission oils are given and their viscosity is, as well as various important properties.

Replacing the oil in the gearbox

The oil for the gearbox is not in all brands of the car to be replaced. There are some expensive models of machines, in which the replacement is not provided for by the manufacturer itself. As a rule, these are cars with a new type of automatic transmission, where the liquid is flooded for the entire service life (which coincides with the service life of the car itself). In such gearbox, it does not even have probe to check the level.

Here, for example, the model of cars in which the replacement is not provided:

  • On German cars, after the 90s of the release, boxes are set without probe;
  • Akura RL with automatic transmission type MJBA;
  • Chevrolet Yukon with Type 6L80 automatic transmission;
  • Ford Mondeo with FMX automatic transmission;
  • Honda CR-V recent years of release and many others

But all this, as if superficially and in practice, things are a little different. It may be necessary to replace if the problem is found in the box. In any case, the diagnosis will be needed (with the definition of a level of scanner and schedule) and the replacement is better to engage in specialists.

Let's leave at the rest of the expensive models of the car and move on to normal. In the boxes of these machines, it is recommended to replace through every 80 thousand km Mileage, which is about 2 years. But here not everything converges. Again, all this refers to the classical, so to speak scenario, implying that the car rarely falls into urban traffic jams, the climate of the country where the driver lives moderate, and the quality of the road does not cause doubts (as in Germany, for example). In our country, where driving conditions are almost extreme, replacement is relevant not every 80 thousand km and not even 40 thousand km of run, but every 25 thousand and these are not loud words, but the realities of our life. Thus, we will take care of the box and do not let her get out of time.

There is another option. Lubrication can be viewed visually and determine its condition. So, if it is noticeable that the fluid has changed the color to the darker or acquired the smell of burned, wait for the planned replacement is already stupid. Urgently contact the service where they will first diagnose, and then oil will be replaced.

Conclusion

Today, the approximate cost of oils for automatic transmission is 250-1000 rubles per liter. The most expensive are French oil Motum ATF, and one cheap is American Chevron ATF. Oils for manual transmission starts from 100 rubles per liter.

Time does not stand still. New varieties of oils appear, import brand products become available, recommendations are changed. Motorist should be aware of the latest events, as well as a specialist in any other area. Periodically check the quality of the oil, diagnose and the status of the box.


The daily route of most motorists is so monotonous that by moving from home to work and on the contrary, crossing the same crossroads, driving the same streets, stopping and starting movement in the same reasons, practically not thinking about the technical side of the trip. A similar illusion of constancy dull attention, and the moment when something went wrong when barely debris breaks in the usual harmony of events, it is completely easy to miss.


How to protect the car gearbox from breakdowns

Specialists recommend at regular trips not to forget to check the level and state of the transmission fluid, reaching the dipstick from after the car will stay in a fixed position for a while. Fresh fluid poured into automatic transmission, has a distinct oil smell and has a bright red color. If so, you can not worry about the technical condition and efficiency of the gearbox of your car. But if the probe shows a reduced level of fluid, or its color resembles the color of the liny linoleum, and the smell has stable burner notes, it should be condensed as soon as possible by changing the transmission fluid, because in this case the gearbox threaten serious trouble.

The first action that should be taken is a general inspection of automatic transmission. Low transmission fluid may indicate leakage in the system. If the leakage is not caused by external damage, but is due to the specifics of the gearbox operation, then, adding the required amount of transmission fluid, can be completely solved by the problem. It should be understood that the volume of the flowable transmission fluid is significantly lower than the amount of engine oil, which is poured into the engine crankcase. In particular, when it comes to a plot.

In most cases, it will be enough to add less than half a liner to the level to reach the desired mark. Often, noticing the lack of a transmission fluid on time and adding it to the desired level, the problems in the operation of the automatic transmission disappear. The confirmation of the fact that there are no serious problems, which will flow from the transparent red liquid of the sweet smell from the automatic automatic transpass. But if when checking the level of transmission it turns out that the liquid in the box has acquired a dark or smoking color, and also has a grown smell, the plot will not do, and the damage of the gearbox will most likely be caused.

Almost all modern automatic type gearboxes, not counting stepless variators, have a zone of the hydrotransformer, which takes direct participation in eliminating the slip and ensuring fuel economy. This mechanism is usually controlled by a special module. Its performance is influenced by such indicators such as the current engine speed, the operating temperature and the position of the throttle valve. If the motor works in traffic along the highway at 500 and more revolutions per minute, it is quite acceptable that the blocking will not happen.

In addition to lowering the fuel consumption, it may have very unpleasant consequences due to overheating of transmission mechanisms. It is recommended to check the connection of the cable that departs from the total wiring harness to the gearbox, including for the absence of its damage.

Perhaps the main way to avoid expensive repairs such a complex unit, as an automatic transmission, will be regular replacement of transmission fluid. It used to be believed that changing the oil in the gearbox should only be in extreme cases, and in the automatic gearbox, the oil did not change. But today, many automakers have abandoned 100,000 thousand and more runs without replacing fluid in transmission, indicating the recommended interval between the replacement of oil in the transmission of 30 thousand kilometers in the automatic operating manual. Particularly relevant, such recommendations for those owners of machines that regularly tow or often exploit their vehicle under full load.


Replacing the transmission fluid in the checkpoint

The process of replacing the oil in the gearbox is not so complicated. This work can be carried out on your own, the truth will be needed to perform several "dirty" procedures. Drain of waste fluid must be carried out in a special container, while it should be waited when the maximum of the large amount of old liquid flows. The problem is that it will not be possible to remove the entire liquid, the considerable part will remain in the torque converter, the clutch drums and other components of the gearbox. But the old transmission fluid contains the burnt particles of the fluid itself and other pollution. To effectively change the oil in the automatic transmission will have to resort to a more complicated type of maintenance.

Deciding not to seek the help of car service specialists to change the transmission fluid and work independently, it is worth thoroughly prepare. First of all, you need to reliably subdominate the car, and it is better to hang the car on the lift. In mandatory, you should block the back pair of wheels.

By unscrewing the pallet cover, it is best not to unscrew a completely several bolts with one of the sides. In this case, it is necessary to understand that the exhaust transmission fluid, whipping out of the gearbox to the resulting slot may sprinkle outside the container installed for draining liquid. To avoid a strong fluid spill, you can use a pump whose hose is immersed through an opening for probe inside the box.

By pumping fluid to the pump, it is possible to significantly reduce the uncontrolled spreading of the spent oil during its plum below. Experts advise to launch the car engine and give it to work for a few seconds to fully drive the waste fluid. Professionals increase the efficiency of the procedure, pouring into a box of fresh liquid with an uncomfortable pallet box. Thus, the fresh transmission fluid almost completely will repel the remnants of "testing".

Drain, you can completely disconnect the pallet. This will be required not only to replace the filter element, but also allows you to remove precipitate and deposit in the pallet itself. In addition, visually inspected the elements of the automatic transmission, it is possible to make certain conclusions about the degree of wear of the box and its possible way out. The presence of metal chips or other garbage is a serious signal indicating fast repair or replacement of the checkpoint.

By installing a new filter, you need to change the sealing gasket. While tightening the pallet mounting bolts, it is necessary to twist them cross with the same initial force. It is recommended to twist the bolts manually until it stops, without the use of wrench.

Often the cause of the transmission box is the deformation of the pallet. In this case, you can try to catch it with a hammer or use a special cork gasket installed on a special sealant. However, it is impossible to "get involved" using sealant, since its excess can penetrate inside the pallet and score the elements of the gearbox.

Many car services and even shops selling automotive oils and accessories offer the service of instantaneous oil replacement. Special machines are used for this. But it is not recommended to use this option, since during the procedure for express oil replacement in the gearbox will remain a significant amount of waste liquid and its sediments, which, dissolved in the freshly "transmission", can cause even greater harm than riding with the old transmission fluid in the box. . The pallet must be cleaned completely.

Replacing transmission oil is the necessary procedure, especially for cars with a manual gearbox. This is a special composition that creates a durable film capable of withstanding very large loads upon contact of the parts.

The role of transmission oil in the checkpoint

Oils are used to lubricate transfer boxes, gearbox gearbox, steering mechanism, transmission of leading bridges and gears, as well as chain gears. Thus, they are used everywhere where it is necessary to transmit a rotating moment or with the help of the oil itself, or by means of gear. The main function, of course, lubricate the friction surfaces, but besides it, transmission oils must perform a number of tasks:

  • due to the formation of a durable film, they prevent wear of rubbing parts;
  • heat removal;
  • corrosion protection;
  • reduce shock loads on contacting gears.

Of course, the transmission oil needs to be changed much less frequently than the motor, but this procedure is also mandatory. Although there are cases when it is not provided for by the car manufacturer, for example, in many machines with a manual transmission, it is necessary to simply regularly check its level and, if necessary, add the desired amount. At the same time, consider that only original oils can be used to not harm your car.

What about the automatic box, so in this case, the oil must be changed every 70,000 km of run, but more accurately this period is stipulated in the technical characteristics of the car and depends on a number of factors, such as operating conditions, climate, automatic transmission.



Replacing transmission oil in mechanical gearbox

In general, it is best to implement this procedure on the lift or on the pit in the garage, but if there is no such possibility, you can use ordinary jacks. In addition, the syringe should be at hand, in order to pour the oil, because it is impossible to make it from the standard container, and the container for the drain of the exhaust oil has already been done.

Further, if you have, then act as follows. To begin with, make a small march, no more than 20 kilometers, it will warm up the old oil, and it will have the desired flow rate, such that it will be quite simple to merge it. Now we leave the car alone by 10, a maximum of 15 minutes, but no more. If possible, we install cars on the pit, the lift, well, or if there are no, raise the jacks.

Next, we unscrew the tube of the oil-tier neck, it will greatly facilitate the entire procedure. By the way, immediately check in what condition is the sealing ring on the lid, change it, if necessary, and its. Then we very carefully turn the cork located on the drain hole, and drain the old waste oil. Watch back the drain hole, and in the oil-free using a syringe pump the required amount of fluid (to the bottom edge). And at the end we wrap the cork.

Replacing oil in automatic transmission

What about, in this case, all initial actions and tools will be identical with the mechanics, the differences will already appear after installing the car to the observation pit. There it is necessary to disconnect the supply hose from the radiator, or rather from its fitting. Then omit this hose into the container, the volume of which should be more than 5 liters. Run the engine on a neutral transmission will thus, a draining of the working fluid will occur, while consider the engine should work for no more than one minute.

After the engine was muffled, we turn the plug from the drain hole and constrain the remnants of the waste liquid. Having wrapped the plug back, the syringe pour 5.5 liters of new oil through the bulk hole, which is located at the top on the crankcase. Next, with the help of a syringe, fill 2 liters of fluid through the liner hose. Run the engine again and drag 3.5 liters of oil through the hose.

Heaving the engine, fill through a 3.5 liter hose and perform two recent procedures until 8 liters of fluid from the supply hose. At the end, we fill the required amount of working fluid in the checkpoint. Note that in no case can no longer pour or less transmission oil, its quantity should be strictly as indicated in the car service book.

Fuel and lubricants for vehicles - Substances that provide functionality extending the service life. Among them are transmission oil. It has certain technical characteristics, physical parameters, component composition. Therefore, you need to know how to choose transmission oil so that it corresponds to the requirements of the vehicle.

What is transmission oil?

Transmission oil - lubricant used for normal functionality of the following car units:

  • mechanical and automatic gearboxes;
  • dispensing boxes;
  • the main gears of the leading bridges;
  • steering mechanism;
  • gearbox.

The substance performs an important role in vehicles, so it is necessary to understand how to choose transmission oil to all systems where it was used, worked as correct as possible, it is proper.

How to choose products?

To find a really effective means, you should consider several important factors. The main thing is in the recommendations of the car manufacturer. The company's advice is recorded in the operating instructions for the vehicle. Having lost it, it is necessary to find the appropriate document on the Internet. It is necessary to try to choose the material by analyzing the characteristics and parameters of the machine.

What do the numbers on the package mean?

The first digits and the English letter W denote the temperature mode of the use of material in winter. The presence of the letter W indicates that the oil can be used in winter, for example SAE 80W. Note SAE 80 says that products are suitable only for the summer, here is the option SAE80W-80 - all-season.

Where and how much poured

The design of the front-wheel drive car implies the location of the tank in the front of the engine connected to the transoxel. Depending on the manufacturer of the vehicle that has developed a transmission system, the material will need 1.5-2.5 liters (may be 2.5-3 liters). Before the transmission oil is pouring into the system, drain the old used lubricant using a drain hole located below the engine compartment of the machine.

When must be changed?

Like, the replacement of transmission oil is mandatory. Preferably change the lubricant once a fifty thousand kilometers of run. This rule contains exceptions depending on the car's mileage, the driver's driving method, the operating conditions of the vehicle. Before choosing a transmission oil and pour it into the system instead of the old one, the above factors should be taken into account so that in the future the car worked as properly as possible, correctly.

How many products are stored?

Storage period does not exceed five years. It is often changing in accordance with the storage conditions of the material. In certain cases, they do not comply with the rules defined by the manufacturer (high or low temperature). If this happens, the shelf life will significantly decrease. This change is often half the period of use of lubricant in vehicle mechanisms of various designs.

Why is the color change?

The transmission oil has the property of cleansing the internal surfaces of parts of gearboxes from various contaminants (plated, spots, divorces, deposits). They are their own shades block the material with certain colors. The process of operation changes the shade of the lubricant - it is becoming more dark, which indicates his work. Before choosing a transmission oil, it is necessary to read its characteristic, parameters, properties to choose the product correctly in the car transmission system.

Why is transmission oil foams?

Transmission oil during work can start foaming. This happens when an increased wear of the internal components is observed, mixing various materials, an overweight lubrication level, the presence of leaks, long-term use with a lack of replacement. In any of the above adverse cases, you need to know how to choose transmission oil and replace it. The lack of this information car will not work properly and reliably. In the near future, without taking anything, there is a breakdown of the power unit.

Shops of oil and auto chemicals from the TAM.BY catalog offer to buy transmission oil for any time of the year different manufacturers at an affordable cost.
