Everything about oil in automatic transmission: Does it take to change it, how to check what and when to fill?

the main / Butter

Automatic gearbox (automatic transmission) is one of the most reliable car units. Its repair is included in warranty service, and car manufacturers try to do everything possible so that it does not fail before the end of the warranty. For the most part, automatic transmissions are designed for a certain period of work, after which they can come into disrepair. It is believed that it is not necessary to change the oil in an automatic transmission. We suggest to figure it out, is it true, and if we replace the oil into the automatic transmission, when?

Any motorist knows that the engine can be changed in the engine, and it has a period of work. After several thousand kilometers, engine oil, filled into the engine, comes in disrepair. This is due to the fact that it works in a medium in which many combustion products are formed. In turn, the transmission oil acts in much more "soft" conditions, and it may be impressed that its replacement is not required.

On this score there are two opinions, each of which has its own rationale:


It should be noted that if we are talking about the variator automatic transmission, the recommendation on the replacement of oil is prescribed in the "passport" of the car. A similar type of transmission does not allow oil to maintain its beneficial properties of more than 60 thousand kilometers, and it should be replaced at this turn, so that the gearbox does not fail.

If you decide to go on the recommendations of the transmission manufacturers and replace the oil in the gearbox, do not do it often often, like. The best option will be the search for information on the frequency of oil replacement specifically in your transmission. Such information can be easily found on the Internet. Most often indicates when changing oil in automatic transmission with standard or severe operating conditions. These figures differ significantly, by about 30%.

Heavy operating conditions ACPP are as follows:


If you find information about the frequency of replacement of oil in the automatic transmission for a specific transmission model failed, it is necessary to be guided by the general recommendations. Most often, the oil change in the automatic transmission is carried out, during the operation of the car under normal conditions, after 60-70 thousand mileage kilometers. It is believed that in older models of cars (up to 2000 release), the oil change in the gearbox is required more often - once every 30-40 thousand mileage kilometers during normal operation.

Attention: If you bought the car "from hand", we advise immediately replace the oil in an automatic transmission or check its quality.

The easiest way to check the oil in an automatic transmission is to take it sample. Determine the "on the sound" or by the nature of the car movement, which requires the change of oil in the box, is almost impossible if it is not about critical cases.

To check the oil in the automatic transmission, you should take a bit of it on the sample and drop on a white sheet of paper or veto. Next, it remains to determine the degree of pollution of oil in color, in accordance with the following rules:

  • Transparent oil. If the oil is transparent, then its replacement is not required. It is not worth paying attention to the color of the oil. In the process of work, the oil of pink can become black, but the main thing is that it remains transparent;
  • Muddy oil. If there is no white sheet through the oil, it means it is contaminated with small particles, and it should be changed. In this situation, the driver can choose a complete replacement of oil or partial;
  • Oil with chips enclosures. If in the sample of the oil, taken from the box, the details of the metal chips or other particles are clearly visible, it means that there will be big problems with transmissions. Also, such oil is distinguished by the caustic smell of Gary. Most often, when the metal chips appears, the oil change can no longer be able to save automatic transmission automatic transmission.

If suspicion is at the beginning of the destruction of the gearbox, you can completely drain the oil and remove the pallet to diagnose the transmission problem. Clean pallet will show that fears were false. If a small metal chips (the so-called "hedgehogs") were nalled on it), it should be understood that the destruction of automatic transmission began, and soon the transmission will stop working properly. Noticing on the pallet obvious pieces of metal, which can be more than 1 mm in diameter, you can diagnose actually destruction of the gearbox and the need for urgent overhaul.

Automatic transmission is an expensive unit, and it is necessary to pour into it strictly such an oil that is recommended by the car manufacturer. If the original oil failed, then it is necessary to find it analogue. In the reference literature of a specific model of the car, as well as on the Internet, always write the name of not only the original oil for automatic transmission, but also its counterpart.

ATTENTION: Fully change the type of oil poured into an automatic transmission, only if there is a complete disassembly of the transmission and a torque converter. Mixing different "varieties" of oil can lead to the destruction of the gearbox.
