Disadvantages of the GM 4T65 gearbox
- This automatic transmission is used with powerful units, and the torque converter clutch wears out quickly;
- The solenoids then become clogged, oil pressure drops, and the clutches begin to burn;
- The clutch drums may also require replacement due to wear of the Teflon rings;
- The bearings are considered a weak point of the transmission; they are often replaced before 200,000 km;
- This is especially true for differential bearings in all-wheel drive versions of the automatic transmission;
- The petal-type oil pump is very sensitive to long-term driving at high speeds;
- At high mileage, the bushings often wear out and the drive chain stretches.
