Disadvantages of the Mitsubishi F4A33 gearbox

  • This is a reliable gearbox, but it is installed with powerful motors and the load on it is heavy.
  • All problems are associated with vibrations due to wear of the torque converter clutches.
  • Vibrations cause bushings to break, resulting in a drop in oil pressure in the system.
  • Due to low lubricant pressure in the transmission, the clutches in the packages begin to burn out.
  • Dirt from the clutches clogs the valve body solenoids and the gearbox stops switching.
