Disadvantages of the AW30-40LS gearbox

  • This is a fairly reliable and durable automatic transmission and has no reliability problems;
  • But if it is overly active, the torque converter locking clutch can quickly wear out;
  • And then the valve body becomes clogged with wear products and the gearbox begins to push;
  • Further, due to shaft vibrations, the oil pump bushing breaks and oil leaks appear;
  • The weak points of this automatic transmission also include speed sensors and selector position sensors.
