Disadvantages of the AW30-50LE gearbox

  • First of all, this is a rare transmission and finding a donor for it is not very easy;
  • But reliability is all right here, breakdowns occur only at high mileage;
  • After 250,000 km, the torque converter locking clutch often wears out;
  • Then this dirt clogs the solenoids and the automatic transmission begins to push when switching;
  • Next, shaft vibrations usually appear, which break the oil pump bushing.
