Disadvantages of the AW30-41LS gearbox

  • This is a very durable automatic transmission and has no problems with reliability;
  • However, this automatic transmission was installed on models whose owners abuse tuning;
  • Therefore, during active driving, the torque converter locking clutch wears out very quickly;
  • And then wear products clog the valve body and sensitive shocks appear;
  • Further, due to shaft vibrations, the oil pump bushing breaks and oil leaks begin.
