Using

Disadvantages of the Aisin AW30-50LE gearbox
- Reliability is fine here; breakdowns only occur at high mileage;
- After 250,000 km, the torque converter lockup clutch often wears out;
- This dirt then clogs the solenoids, and the automatic transmission begins to jolt when shifting;
- Shaft vibrations usually appear next, which damage the oil pump bushing.
