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.
