Technical issues and repair guidelines
This transmission is a rare “guest” in repair services, thus it can be assumed that this unit is quite reliable. It went through many upgrades without serious changes (only rarely updating gaskets, seals, and filters). Clutch and brake packages are designed very reliably with such a huge reserve, that the type of friction elements hasn’t been changed since 1965.
The Direct clutch pack is the first to be worn-out and considered to be one of the weakest clutch packs. But it is quite normal and occurs after considerable mileages, extreme operating conditions and loads. If friction components of two abovementioned packs burn ATF for a long time and this ATF soaks in other friction linings, then the whole set of friction components should be replaced.
After 12-15 years of usage the wear-out of bushings becomes clear and vibrations exceed allowed limit, therefore repair specialists have to replace the whole set of bushings. Solenoids and the torque converter lock-up solenoid also reach the end of their service life by time. Almost all overhauls are performed when bushings, hollow discs, solenoids reach the end of their long service life. These transmissions easily operate for 200 thousand kilometers and even longer.
