1. Level check transmission fluid

For most gearboxes, the optimal oil level is between the ADD and FULL marks on the dipstick hydraulic system Automatic transmission, at normal operating oil temperature 66 - 93C. This temperature is reached after the car has driven at least 13-25 km.
Note. If the vehicle has been used for a long time high speeds or when high temperature ambient air, the correct oil level in the automatic transmission can only be measured 30 minutes after stopping the car engine. This time is necessary for the oil to cool.

The oil level in an automatic transmission can be checked both at normal operating oil temperature and at room temperature. When checking the oil level and, if necessary, bringing it to the optimal level by adding oil, you should be careful not to overfill the automatic transmission hydraulic system with excess oil, which leads to its foaming and pouring out through the breather.
1. The car is installed on a flat horizontal surface, the engine is running at speed idle move, the wheels are locked by the brake. While holding down the brake pedal, the driver sequentially moves the gear shift lever to all its positions in order to fill the lines of the automatic transmission hydraulic system with oil.
2. Set the gear shift lever to position P (parking). On some automatic transmission models, the lever is set to position N (neutral). Release the brake pedal. Extract from filler neck Automatic transmission dipstick, wipe it dry and reinsert it into the neck until it stops.
3. Remove the dipstick from the neck and check the oil level using it. The level should be between the ADD and FULL marks on the dipstick. If necessary, add oil. After each topping up, carry out operations according to paragraphs. 1.2 and then measure the oil level again.
4. Insert the dipstick into the neck all the way so that it seals tightly with its lid to prevent dirt, water, etc. from getting into the automatic transmission.

The technique for measuring the oil level at room temperature (cold oil) is exactly the same as at normal operating temperature. Only the oil level on the dipstick in this case should be at the level of the ADD mark.
Note. Many dipsticks have either one or two markings in the form of dimples or through holes to indicate the level of cold oil, while others have markings in the form of COLD (cold) and HOT (hot) to indicate the level, respectively, of cold and warmed up to normal operating temperature oils
Attention! When measuring the cold oil level and bringing it to the optimal level, you should be especially careful not to overfill the automatic transmission hydraulic system with excess oil. Remember that the oil level on the dipstick when bringing its temperature to normal operating temperature is 0.6 - 0.7 cm higher than the level of the same amount of cold oil.

Problems associated with overfilling the automatic transmission hydraulic system.
When the automatic transmission hydraulic system is overfilled with excess oil, rotation with high speed internal components of the automatic transmission leads to oil foaming. Foamed oil, due to the air in it, cannot compress the drive and driven discs in the clutch packs with the required force, which leads to their slipping and combustion, that is, failure of the automatic transmission. A similar situation is observed in brake system vehicle when air gets into it. Foamed oil also flows out of the automatic transmission through the breather.

Problems associated with insufficient oil in the automatic transmission hydraulic system.
Due to insufficient amount of oil in the automatic transmission pan oil pump pumps oil along with air into the lines of the automatic transmission hydraulic system. Similar to what was said above, the oil does not compress the clutch discs properly. The result is the same - the disks slip relative to each other and burn out.

2. Assessing the condition of the automatic transmission according to appearance transmission fluid.

Transmission fluids or oils (in English - automatic transmission fluid or abbreviated - ATF) in automatic transmissions perform several functions at once, namely:
- transmit torque from the torque converter pump wheel connected to the engine to the turbine wheel connected to input shaft automatic transmission;
- are the working fluid, under the pressure of which the drive and driven disks in the clutch packs are compressed together, the servos that clamp the brake bands are turned on, which makes it possible to turn on (off) various transmissions in automatic transmission;
- lubricate gears, bearings and bearings;
- carry out heat removal from the automatic transmission during its operation.
The most common brands of transmission fluids are DEXRON II, DEXRON III. Manufacturers that produce gear oils under other names usually indicate that their products comply with the DEXRON standard.

The color and smell of its transmission fluid (oil) can tell a lot about the condition of the automatic transmission. In a working automatic transmission, the oil has a thick red or orange-red color. The dark brown or black color of the oil, combined with its burnt smell, convincingly indicates an obvious problem in the box.
Note. If, at the initial stage of automatic transmission operation after starting the engine, the oil acquires a brownish-greenish tint and an unpleasant, but not burnt, smell, this is considered normal and is not a sign of any malfunction in the automatic transmission.

When the clutches are destroyed, brake bands, bearings, gears, metal particles, black or brown particles of the destroyed friction layer will be present in the oil. Some part of all this will definitely settle on the dipstick along with the oil. If the oil on the dipstick removed from the automatic transmission looks like a white-pink emulsion, this is a sign that water or antifreeze has got into the oil. If such signs are detected, it is necessary to remove the automatic transmission oil pan and carefully examine it for any deposits. If the oil in the pan is dirty or liquefied, or there are solid particles of anything in it, the automatic transmission must be immediately removed, disassembled, cleaned and repaired. In addition, it is imperative to flush the automatic transmission cooling system.

3. Assessing the condition of the automatic transmission when the vehicle is moving

The task of detecting a malfunction in an automatic transmission is greatly simplified if the driver of a car with an automatic transmission, in as much detail as possible, to the best of his technical knowledge and driving experience, tells the specialist about the symptoms of the “disease” of the transmission, be it suspicious noises, oil leaks, insufficiently fast acceleration of the car or jerks when shifting gears . It is in the interests of the owner, primarily economic, that if the slightest malfunction is detected, immediately contact a specialist. Yes, automatic transmission diagnostics will cost something, but by an order of magnitude less repairs the box "flyed" due to an oversight. Do not hesitate to ask the specialists questions about the design features, maintenance, operation, and even about the features of driving your particular car with just such an automatic transmission. Following the recommendations of professionals will not cost you anything, but will significantly add “life” to your box and save you enough money.

Checking the condition of the torque converter.

Most characteristic malfunctions torque converter (CT), which are detected when the car is moving, are either the unlocking of the one-way clutch, when it rotates freely around its axis in both directions, or its complete jamming. Let us remind you that a working overrunning clutch should rotate, but only in one direction.
A sign that the overrunning clutch rotates freely in both directions is poor overclocking vehicle from a standstill to a speed of approximately 30-45 mph (48-72 km/h). After the vehicle reaches this speed, the automatic transmission then operates normally. To check that the cause is in the GT and not in the engine, proceed as follows. With the gear shift lever in position N (neutral), press the gas pedal to increase engine speed. If the engine “responds” to pressing the pedal with an increase in speed, it means that the fault is not in it, but in the GT.
If your car accelerates normally from a standstill, but from the moment it reaches a certain speed it refuses to go faster despite the fact that you vigorously press the gas pedal, this indicates that the clutch in the GT is stuck. In this case, the engine and GT will overheat. An overheated GT has a bluish tint.

When driving a car with a working automatic transmission, when you press and release the gas pedal, gear shifting should be carried out consistently and smoothly, without jolts, jerks or slipping. It is necessary to monitor the speed at which the vehicle engages (disengages) one or another gear. Slipping, jerking, delays when shifting gears or the complete absence of any gear indicate that the automatic transmission urgently needs repair.

4. Extraneous noise in automatic transmission

When assessing the condition of the automatic transmission both in a moving (road test) and in a stationary (stall speed test) car, the driver should carefully listen to the sound of operation power unit(engine and gearbox). If suspicious noises are clearly audible in the smooth, monotonous sound of the power unit, this may be the result of a malfunction in both the engine and the automatic transmission. Malfunctions that are not related to the automatic transmission and produce non-standard sounds include problems with the water pump, air conditioning compressor, generator, steering column, etc. If it is definitely established that the box is “rattling,” then an experienced specialist can roughly determine the nature of the malfunction based on the timbre and tone of the noise.
For example:
1) A howling sound, like a siren. It is considered normal if such a sound appears briefly in the GT during a stall speed test and subsequently disappears.
2) A constant howling sound (the car is stationary), which increases or decreases depending on the number of engine revolutions, indicates that the automatic transmission may be:
- insufficient oil level;
- air entering the oil pump due to wear of the sealing gaskets and rings;
- damage or wear of oil pump gears;
- the gears were incorrectly inserted into the pump housing during its assembly;
- incorrect gear engagement in the pump.
3) The whirring sound is the result of either vibration of the linear oil pressure control valve spool, or the movement of some broken or worn seal. The strength of the sound also depends on the engine speed.
4) Constant rattling sound - usually happens on low revs engine and indicates a malfunction in the GT (breakage of pump blades, turbine wheels or damper springs).
5) An intermittent rattling sound in a moving car at low engine speeds is a sign that the engine flywheel to which the GT is attached is damaged. When you move the gearshift lever to N or P, the sound may disappear for a short time.
6) If extraneous sound is present in one gear and disappears when other gears are engaged, therefore, one of the planetary gears operating in this gear is faulty. If, when you turn on other gears, the extraneous sound does not disappear, but only changes its tone, most likely the malfunction lies in thrust bearings or inserts.
7) The impression that the engine is vibrating can be caused by vibration of the supply pipes or oil cooling line pipes in the automatic transmission due to breakage or disconnection of the brackets securing them.

Of course, it is not possible to describe all non-standard noises that may arise during operation of an automatic transmission. This chapter lists only the most frequently encountered ones.

Every modern car with an automatic transmission needs timely and, most importantly, quality service. In this article we will talk about how to properly check the oil level in an automatic transmission on a Toyota, and we will also tell you why you need to check the level, what problems can be caused by low or high level oil in box.

How to check correctly?

As a rule, checking the amount of oil on Japanese automatic gearboxes is carried out with the engine running and the “P” mode set. Almost all drivers who drive an automatic transmission know that the “P” mode means parking. The photo shows the shift lever automatic transmission Toyota Corollas.

Next, after starting the engine and putting it in parking mode, we find the location of the dipstick in our car. This is very easy to do - you just need to scroll through some technical documentation and find its location in your car. Or you can pay attention to the picture below and see where this probe is approximately located.

Having found it, we take it out and wipe it with a dry cloth, preferably one that does not have lint. After we wiped it off we can see some marks on it. As a rule, there are only two of them: the first is COOL. This mark is used to check the oil on unstarted vehicles. It is advisable that the car not be driven for at least 4-5 hours before the inspection. The second mark is HOT. This mark is intended to check the oil level when the machine engine is running. In the photo below you can see how and where the marks are located.

Having seen the marks, it is worth saying that although there are two marks there, it is best to check the level with the engine running and preferably warmed up to the average normal temperature. Typically it is 90 degrees Celsius.

So, we warmed up the car, pulled out and wiped the dipstick, put it back in its place, wait a few seconds and pull it out again. The level should be clearly visible on it lubricant in your Corolla's automatic transmission.

If its level is below the HOT mark, then it is worth adding it little by little with the engine off. Then, check again by performing the above procedure again. After the lubricant has been added and its level is back to normal, we install the dipstick in its place and we can drive without problems. This completes the automatic transmission check procedure. Now it’s worth talking about the problems that can arise from a lack of lubricant in the box or, conversely, from its excess.

Automatic transmission problems on Toyota Corolla

A small amount of lubricant in the box can lead to a huge number of problems. As a rule, when its level is low, the pump pumping oil starts with working fluid capture air. As a result of this process, an emulsion is formed that compresses very well. The oil begins to lose one of the most the most important properties– it becomes easily compressible under good pressure. And this already leads to the emergence of such problems as:

• Poor heat dissipation from the automatic gearbox;
• Low oil pressure in the system;
• The lubrication of the working parts of the automatic transmission deteriorates, which in turn very quickly disables the box, etc.

Therefore, you should carefully monitor the amount of oil in the automatic transmission of your car, otherwise you will have to pay a lot of money for its restoration and repair because of some little thing.

An excess can lead to increased load on the oil pump, as a result of which it can easily fail. And since they are not repairable, replacing it can cost a lot. Having dealt with possible problems, let's talk about how much oil needs to be poured into the box and what volume is optimal for the normal operation of the box.

How much lubricant to pour into an automatic transmission on a Toyota Corolla?

As a rule, Corolla owners change an average of 4 to 5.5 liters. The volume depends on the type of automatic transmission, on the model of the car itself, since in the model different years Different automatic machines can be installed, with different numbers of gears, etc.

In order to know exactly required amount lubricant, you need to read the technical documentation and find out the requirements set by the manufacturer for of this car. After the material is poured, we start the car, warm it up and be sure to check its quantity on our dipstick. If the level is lower, then you need to add oil; if the level is higher, then you need to drain the oil a little. Therefore, we need to achieve the ideal level for your box. Thanks to this process your car will delight you with its durability and quality of service.

Replacing and checking the transmission fluid level in a Toyota automatic transmission

It is necessary to check the oil level in a Toyota automatic transmission regularly. This will make it possible to prevent problems with the machine and will allow you to avoid spending money on expensive repairs to the unit. If you do not have the opportunity to regularly go to a car service center, check the oil level and fill in the oil product yourself.

Many inexperienced motorists want to know the answer to the question, what is the frequency of checking the oil level in a Toyota Corolla automatic transmission. Inspection intervals depend on air temperature and oil heating temperature.

If the car is used in ideal conditions, then the oil in the box needs to be replaced every one hundred and sixty thousand kilometers. In reality, automatic transmission oil needs to be changed every forty to sixty thousand kilometers. The frequency of checks is significantly reduced if you regularly drive off-road or operate the car in winter.

Verification procedure

Before adding fresh oil, you need to check the oil level in the automatic transmission. For this:

1. Place the car on a level place.
2. When the engine is idling, grab the gearbox handle and change gears. Return the lever to its original position.
3. Remove the dipstick from the box. Wipe it with a dry cloth and put it in a special socket.
4. Remove the dipstick from the automatic transmission. This must be done with an engine running on idle speed.
5. There is a “HOT” mark on the dipstick. If the engine is hot, the lubricant level should be at this mark. Top up the automatic transmission oil if necessary.

Probe with markings for automatic transmission

Pay attention to the color of the oil and its smell. If it smells burnt, it needs replacement. As you can see, there is nothing difficult about checking the oil volume in an automatic transmission yourself.

Changing the oil fluid

Changing the oil in a Toyota Corolla automatic transmission is divided into three types:

1. Intermediate. It is carried out to remove used lubricant and fill in fresh petroleum product.
2. Standard. This is carried out if the lubricant poured into the Toyota transmission has exhausted its life.
3. Full download.

An intermediate oil change for a Toyota Camry takes place in several stages. First of all, the waste is drained. Then fresh consumables are poured into the gearbox. It is necessary to dismantle and thoroughly wash the transmission pan and oil filter.

Color transmission oil

The standard shift is more difficult to perform than the intermediate shift. First, the spent oil product is removed (drained through a special hole). After this, the pan and oil filter are removed from the Corolla gearbox. The filter element is replaced, the pan is mounted in place. Only after this does fresh oil flow into the transmission.

The scheme for completely pumping lubricant into a Corolla automatic transmission involves the use of special equipment. Correctly connect the equipment to the oil filler neck, pump out the waste, and then pump in new motor oil under pressure.

Procedure for changing transmission oil

In order to correctly change the oil product in an automatic transmission, you will need:

• 1 liter of gasoline;
• set of tools;
• fresh gear oil;
• narrow funnel;
• compressor.

The algorithm below is time-tested and allows in the right way change oily liquid in transmission:

1. Warm up the engine. Unscrew the transmission cover.
2. Remove the pallet by unscrewing the special bolts. Check if you have dented it during dismantling.
3. Be careful not to deform the pad. IN mandatory Wear gloves to avoid getting burned by hot used motor oil.
4. Unscrew the differential plug. Wash it with gasoline.
5. Change the oil filter. Mount the pallet.
6. Screw on the caps and pour in fresh consumables.
7. Warm up the engine. The transmission handle must be switched in all modes. Stop in each gear for ten seconds. Check the amount of lubricant in the gearbox. You should already know how to check the oil level in a Toyota automatic transmission.
8. Check to see if grease is leaking through the pan cover. If you performed the replacement correctly, this shouldn't happen.

Oil level in Toyota automatic transmission - logbook Toyota Corolla RoboJapanese 2007 on DRIVE2

Many owners do not even realize that from time to time they need to check the oil level in the Toyota automatic transmission, since the normal functioning of the automatic transmission will depend on this. The thing is that in winter, when the car frequently slips or gets stuck, the liquid (oil) gets very hot, which leads to its expansion and as a result it can be squeezed out. An inattentive car owner may not notice this and fail to replenish the missing fluid, thereby exposing correct level Toyota automatic transmission oils.

When replacing fluid in an automatic transmission Toyota cars It is not enough to simply drain the old oil and add the same amount. After replacement, it is important to set the correct oil level in the automatic transmission; this is done with the automatic transmission warmed up to operating temperature of 80 degrees.

Important terms:

1. Check the oil level only on a flat surface2. With the engine running in position P

3. Before checking the oil level in a Toyota automatic transmission, you need to go through all the positions of the automatic transmission, that is, from P to L and back (slowly, with a delay)

Every modern car with an automatic transmission needs timely and, most importantly, quality service. In this article we will talk about how to properly check the oil level in an automatic transmission on a Toyota, and also tell you why you need to check the level, what problems can be caused by low or high oil levels in the box.

How to check correctly?

As a rule, checking the amount of oil on Japanese automatic gearboxes is carried out with the engine running and the “P” mode set. Almost all drivers who drive an automatic transmission know that the “P” mode means parking. The photo shows the shift lever for a Toyota Corolla automatic transmission.

Next, after starting the engine and putting it in parking mode, we find the location of the dipstick in our car.

So, we warmed up the car, pulled out and wiped the dipstick, put it back in its place, wait a few seconds and pull it out again. It should clearly show the lubricant level in the automatic gearbox of your Corolla.

If its level is below the HOT mark, then it is worth adding it little by little with the engine off. Then, check again by performing the above procedure again. After the lubricant has been added and its level is back to normal, we install the dipstick in its place and we can drive without problems. This completes the automatic transmission check procedure. Now it’s worth talking about the problems that can arise from a lack of lubricant in the box or, conversely, from its excess.

Automatic transmission problems on Toyota Corolla

A small amount of lubricant in the box can lead to a huge number of problems. As a rule, when its level is low, the pump pumping oil begins to capture air along with the working fluid. As a result of this process, an emulsion is formed that compresses very well. The oil begins to lose one of its most important properties - it becomes easily compressible under good pressure. And this already leads to the emergence of such problems as:

• Poor heat dissipation from the automatic gearbox;

Therefore, you should carefully monitor the amount of oil in the automatic transmission of your car, otherwise you will have to pay a lot of money for its restoration and repair because of some little thing.

An excess can lead to increased load on the oil pump, as a result of which it can easily fail. And since they are not repairable, replacing it can cost a lot. Having dealt with possible problems, let's talk about how much oil needs to be poured into the box and what volume is optimal for the normal operation of the box.

How much lubricant to pour into an automatic transmission on a Toyota Corolla?

As a rule, Corolla owners change an average of 4 to 5.5 liters. The volume depends on the type of automatic transmission, on the model of the car itself, since models of different years may have different automatic transmissions installed, with a different number of gears, etc.

In order to know exactly the required amount of lubricant, you need to read the technical documentation and find out the requirements set by the manufacturer for a given vehicle. After the material is poured, we start the car, warm it up and be sure to check its quantity on our dipstick.

Thanks to this process, your car will enjoy its durability and quality of service.

Automatic transmission fluid is a very special oil. It has unique characteristics and must retain its properties at temperatures from -40 to +400 degrees. Oil not only serves to lubricate automatic transmission mechanisms, it helps cool the box and is a working fluid. It is the oil that transmits torque from the engine to the wheels of the car through the automatic transmission. And due to the oil, gears are switched. Without oil, the automatic transmission simply will not work, and if something is wrong with it, it will quickly fail. Therefore, to prevent the car from becoming real estate, it is necessary to carefully monitor the level and condition of the oil.

Oils for automatic transmissions of different cars

Symptoms of most automatic transmission problems include abnormal operation:

• the dynamics drop, the behavior of the car and its acceleration characteristics change;
• when changing gears there are jerks and delays;
• one or more gears disappear;
• The box's self-diagnosis system shows errors on the dashboard;
• the car does not move when the gear is engaged;
• the box makes strange sounds: howling, crackling, grinding, banging, and so on.

How to check the oil level in an automatic transmission?

Diagnosis of any changes in automatic transmission operation begins with diagnosing the condition of the oil.

In most cars, checking the oil level in the automatic transmission is quite simple.

The procedure looks like this:

On some automatic transmissions, measurement rules may differ. For example, you can correctly determine the oil level in them only when it is cold. In such automatic transmissions, only the inscription COLD is present on the dipstick. On some probes, the marks may not be related to temperature conditions at all and have a different designation (for example, OK), or they may simply be notches or non-letter marks on the probe. In some cars, the measurement is carried out with the engine running or the gearbox selector position in neutral.

On modern automatic transmissions there may not be a dipstick at all. Manufacturers began to make their transmissions maintenance-free. That is, the oil in them is designed for the entire service life of the car or until the first overhaul. Some such automatic transmissions actually fulfill the manufacturer’s claims. But not all. In addition, most drivers drive cars with automatic transmission completely incorrectly and subject them to unnecessary loads. Add to this the sharply continental climate: driving in two-hour traffic jams at a temperature of +40 or driving at -40 with constant warm-ups and slipping on ice and snow.

Car while driving on a snowy road

As a result, the oil in unattended automatic transmissions behaves exactly the same as in serviced ones. It turns black, becomes saturated with fragments and remains of the box mechanisms, and becomes contaminated with the remains of plastic and rubber. And it loses its properties, which further leads to failure of the transmission. They say about such boxes that you really don’t have to change the oil for 200,000 kilometers, it’s just that then, along with the oil change, the box itself changes.

Fortunately, you can still change the oil or simply monitor its level on such cars. Instead of a dipstick, they have a control hole through which the oil level is correctly set if the box needs to be repaired.

The measurement procedure on such vehicles is as follows:

1. The automatic transmission warms up, for this purpose the car is driven from 5 to 20 kilometers.
2. Then the car is driven onto a horizontal platform. But this is provided that in order to get to the control hole you do not need a hole or a lift.
3. The plug is unscrewed. If the oil spills out, its level is fine. It is better to use a container and see how much has spilled out - the level may be higher than normal. If the oil does not flow, it means that it needs to be added.

Adding oil to a maintenance-free automatic transmission when its level is low

If the oil level in the box is low, it must be topped up immediately. The box itself cannot consume oil like an engine. If the level has dropped significantly or drops constantly, it means there is a leak somewhere in the box. Low level oils are very bad for the box. Those mechanisms and parts that do not receive enough oil begin to burn and fail. Low oil level leads to failure temperature regime, sharp decline service life of the automatic transmission, reduction of pressure in the automatic transmission and breakdown of its individual parts. Without oil, the gearbox can only travel a short distance and this kind of abuse ends very, very badly. expensive repairs. The consequences can be very different - from none to complete replacement machine.

If the oil level in the automatic transmission is too high, this is also bad. If it is higher than normal, the oil begins to foam and loses its properties. The effect is the same as with understated.

Do not confuse foamed oil with individual air bubbles. Their appearance is almost normal and occurs when the dipstick is removed. Foamed oil is uniform in structure. Various oils They have different smells, but none of them smell like burning. They also differ in color.

Draining waste dirty oil from automatic transmission

But during the operation of the car, the oil inevitably darkens, becomes cloudy and crumbs and small metal filings appear in it. When changing the oil, it is worth remembering its original color.

Dirty oil can cause irreparable damage to the box. Metal particles in the oil will begin to abrasively treat all the insides of the box, and the valve body will be the first to suffer. It will begin to produce abnormal pressure, which will lead to an expansion of the list of breakdowns. Sooner or later, some clutch pack will burn out and its adhesive base will get into the oil, which will saturate the remaining clutches and very soon they will all fail. Minor symptoms will develop in progression until one day the box simply dies. And it is likely that there will be nothing left to repair in it.

How to check the oil level in automatic transmissions of popular car brands. Tips and Features

Toyota Corolla and Camry v40

The transmission oil level for Toyota Corolla and Camry v40 is measured only when the car is warm; it cannot be measured when it is cold. To do this, you need to drive a Toyota Corolla and Camry v40 for at least 5 kilometers. After the engine warms up, the Toyota Corolla and Camry v40 selector lever is set to position P.

Measuring oil in automatic transmissions of Toyota Corolla and Camry v40 should be carried out on a flat piece of ground. Under the hood of the Toyota Corolla and Camry v40 you need to find an oil dipstick. In order to check the oil level after a trip to the Toyota Corolla and Camry v40, you need to wipe the dipstick with a rag. On the Toyota Corolla and Camry v40 dipstick there will be two marks HOT and COLD. We will be interested in the HOT mark, which will show what the oil level is in warmed-up Toyota Corolla and Camry v40 cars.

Toyota Prado 120

Toyota Prado 120 does not have a dipstick for measuring the oil level; this automatic transmission is maintenance-free. But in Russian conditions, it is better to change the oil on the Prado 120 once every 80,000 kilometers. The oil measurement algorithm in the Prado 120 is similar to other automatic transmissions without a dipstick. If the oil level in the Prado 120 automatic transmission is higher than normal, this is a sign of a malfunction in the gearbox.

Chevrolet Cruze

In the Chevrolet Cruze automatic transmission there is no dipstick for measuring oil. The automatic transmission of the Chevrolet Cruze is maintenance-free; manufacturers claim that the oil will be enough for the long life of the car. Despite this, the level and condition of the Chevrolet Cruze automatic transmission oil can still be checked. To do this, you need to lift the Chevrolet Cruze on a lift and find the control plug on the automatic transmission.

After the Chevrolet Cruze control plug is unscrewed, oil will flow out, and if it does not flow, it means that the oil level in the Chevrolet Cruze automatic transmission is insufficient. If the oil level in the Chevrolet Cruze automatic transmission is normal, then it will still not be superfluous to check its condition. You can add oil to the Chevrolet Cruze automatic transmission through the breather in the upper part of the box.

Peugeot 206, 307, 308, Renault Sandero and Citroen C4

Peugeot models 206, 307, 308, Renault Sandero and Citroen C4 are equipped with AL4 automatic transmission. Automatic transmissions of Peugeot 206, 307, 308, Renault Sandero and Citroen C4 are maintenance-free. However, due to design features Automatic transmissions of Peugeot 206, 307, 308 and Renault Sandero are very sensitive to the condition of the oil. Gearboxes Peugeot 206, 307, 308 and Renault Sandero with insufficient level oils overheat and fail. You can measure the oil level in automatic transmissions of Peugeot 206, 307, 308 and Renault Sandero using the inspection hole. The procedure for measuring the oil level on automatic transmissions of Peugeot 206, 307, 308 and Renault Sandero is similar to other maintenance-free gearboxes. To measure the automatic transmission of Peugeot 206, 307, 308 and Renault Sandero, you need to warm it up after driving at least 5 kilometers. Service station specialists recommend that before taking measurements, sequentially switch the automatic transmission selector of Peugeot 206, 307, 308, Renault Sandero and Citroen C4 to all positions, holding each position for 30–60 seconds.

Ford Focus

Ford Focus automatic transmission is maintenance free. The oil in the Ford Focus automatic transmission is designed until the first major overhaul - this is approximately 120,000 kilometers. The Ford Focus automatic transmission has a control hole through which the oil level is measured. To measure, you need to warm up the Ford Focus automatic transmission; it is impossible to correctly determine the level when it is cold.
