In order for the automatic transmission to be a long time, it is necessary to ensure that the level of the working fluid does not fall and is not too high, and the liquid itself remains in the correct condition. If these conditions are met, the lifetime of the ACPR will be comparable to that of the whole vehicle.
To avoid breakdowns, it is necessary not only to keep track of the level and purity of the liquid, but also to know which brand and type ATF is used in the "machine"
Unfortunately, these simple conditions are not always respected. The fluid often changes in a bad time and is wrong, the driver's level is rarely monitored, and if the liquid is poured into the "machine", they do not know what type of ATF is used in it. The result of this negligence has been the stereotype that has arisen with regard to the reliability of ACPR.
In order to avoid breakdowns, it is necessary not only to keep track of the level and purity of the liquid, but also to know which brand and type ATF is used in the "machine", since this depends to a large extent both the properties of the liquid and the period during which it can be used before being replaced.
How often do you replace the oil in the ACPR?
It's important to change the oil on time. However, the notion of "timely" for different boxes may be very different. Replacement intervals are described in the vehicle's manual. By looking at it, you can generally see two digits-the replacement interval in normal and difficult operating conditions. Under difficult conditions, the interval, according to some manufacturers, should be twice as short.

The general recommendations can only be very approximate: in motor vehicles up to the 2000s the replacement interval is between 30 and 60,000 kilometers. In newer machines-from 80 to infinity. What are the harsh conditions for the operation of ACPR?
What are the harsh conditions for the operation of ACPR?
"Heavy operating conditions", which provide for more frequent replacement of the liquid, include:
- Permanent hauling of motor vehicles and trailers; transport of heavy loads, frequent travels with a complete set of passengers in the passenger compartment.
- Prolonging on roads with dirt, sand or snow, especially in the cross-season.
- Operation of a vehicle at a high or low temperature for a long time.
- The work of the start-stop system in traffic jams; daily operation in the city.
- A dynamic style of driving.

Private case of replacement intervals by manufacturer's recommendation
Private case of replacement intervals by manufacturer's recommendation
The requirements for replacing transmission fluid on Toyota's vehicles may be considered a private matter in the question of oil replacement in ACPR.
As a rule, in Toyota production up to 99 years of oil, it is recommended to change every 60,000 kilometers under normal conditions and in difficult conditions every 30 thousand.
If we look at the case of Toyota Genuine ATF type T-IV or Toyota Genuine ATF WS, Toyota's replacement term is no less than 90,000 km away from the more modern Toyota Genuine ATF type T-IV or Toyota Genuine ATF WS. In normal conditions, there is no need to change liquid, only to keep track of it. It turns out that the oil change is only necessary if there is a suspicion that the liquid has for some reason lost its properties, for example, after overheating.
The use of oil throughout the life of the service has become a common event for producers these days. True, it often leads to the fact that the user simply does not understand that such heavy operating conditions, in which the oil still needs to change.
What kind of oil do you have in ACPR?
Recommendations for make and type of oil are also contained in the operating instructions. To replace the modern ATF Toyota WS, the obsolete Dexron III, for the purposes of economy, is by no means possible. If there is a Dexron II written in the manslaughter, then Dexron II can be poured into Dexron II or Dexron III. The inverse sequence is not valid-together with Toyota Genuine ATF type T-IV Dexron III cannot be used due to the threat of withdrawal of the ACPR.
Of course, in addition to the OEM liquids with the manufacturer's brand, there are also cheaper substitutes that suit your box, but for a qualified choice you need to understand the specifications in detail. If you have no confidence in your own knowledge, the only safe exit is to use the original ATF.

What else to buy when you replace the ATF
All necessary replacements are available at the dealer's service. However, if you choose to use an alternative workshop, it will not be necessary to buy the ACPR filter and the pallet of its crater. When the liquid is completely replaced, the pallet is removed and the new gasket will guarantee the leakproofness of the connection after the replacement. The filter is directly above the pallet, and the best reason to replace it is not to be found, given the sufficient length of the interval.
