Disadvantages of the AW35-50LS gearbox

  • This is a fairly reliable automatic transmission and breakdowns occur only at high mileage;
  • It all starts after severe wear of the torque converter locking clutch;
  • Then wear products clog the valve body and shocks appear when switching;
  • Then the vibrations of the shaft break the oil pump bushing and oil leaks appear;
  • It is also important to keep the cooling system clean; this automatic transmission does not tolerate overheating.
