Disadvantages of the AW30-40LE gearbox

  • This automatic transmission has a huge resource and breakdowns occur only at high mileage;
  • Problems begin after the torque converter lock-up clutches wear out;
  • Shaft vibrations break the oil pump bushing, and dirty oil clogs the solenoids;
  • Electrically, speed sensors, selector lever positions and ECUs are often changed;
  • The control cable may also break, replacing which is quite labor-intensive.
