Disadvantages of the Toyota A650E gearbox
- This is a very reliable automatic transmission and problems occur only at high mileage;
- It all starts with critical wear of the torque converter lockup clutch;
- The wear debris then clogs the valve body and jerking appears when shifting;
- Shaft vibrations usually appear next, and they destroy the oil pump bushing;
- It is also recommended to watch the cooling system, as this gearbox does not tolerate overheating.
