Technical issues and repair guidelines
This transmission has almost flawlessly matched gear ratio, tested cooling and ATF heating systems. The acceleration in the sport mode turns on slipping torque converter lockup starting at the 3-rd gear. It doubles the time before the torque converter repair in comparison with competing 6HP26 units.
The fluid change (Toyota WS) and filter replacement in A750 is performed with the help of partial and full replacement methods. The transmission electrics has delicate settings and sensitive to the oil level. Solenoids of this transmission can exhaust its resource prematurely and often get replaced, especially in gearboxes during first two years of series production. But in general, this transmission as well as majority of rear-drive Aisin automatic transmissions was produced to be "invincible".
Typical problems in A750E
The most common ordered repair kits for the first overhaul of the А750F unit, includes the following:
- Kit of gaskets and seals, Overhaul Kit
- Kit of all friction components
Overhauls of long-time neglected transmissions are notable for the fact that friction components should be replaced with all solenoids. The first package that gets burnt with cover plates: Forward С1 frictions. Then comes the turn of the В1 braking package.Other frequently burning frictions are located in Direct, C3 and 2nd brake packages.
Different problems with the torque converter, valve body and solenoids may occur as a result of long-time overheating or aggressive driving style on the off-road territory or on snow after 70 - 80 thousand kilometers.Transmission operation with worn-out torque converter clutch may lead to vibrations and fluid leakages through the pump seal. At the same time, the problem with the pump bushing occurs, and later you will have to deal with the pump failure. Valve bodies of А750, А761 and А960 have been constantly modified, improving their design, therefore selection of valve bodies and solenoids for replacement is performed specifically for each car according to its VIN-code. In general, the А750F unit is adjusted quite accurately for the torque converter and the valve body. Afterwards, you can drive for 150-200 thousand kilometers without serious problems for car owners, if ATF condition is controlled.
