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.
