4T65E Transmission Problems
The weak point of automatic gearbox 4T65E is bearings, which can come into disrepair already on the run at 150 — 200 thousand kilometers. As a rule, when the car gets this operational kilometer there is a need of major repair of gearbox. The major repair is a certain complexity due to the need to dismantle the gearbox from the car and carrying out repair works on the special stand. In some cases, it can be observed oil leaking out of the defective gaskets. In this case, the repair of gearbox consists in replacement of the rubber gaskets and cleaning the oil. Quite often there are problems with drum clutch which at aggressive driving burns quickly and needs to be replaced.
