Disadvantages of the Mitsubishi V4AW3 gearbox
- This automatic transmission has a huge resource and the described problems happen at high mileage.
- Here the torque converter bushing rotates due to wear on its locking clutch.
- Due to very dirty oil, the solenoids may simply get stuck in one of the positions.
- Quite often, speed sensors, selector position sensors and automatic transmission ECUs fail.
- Also, the control cable often breaks, and replacing it is very labor-intensive.
