Disadvantages of the Toyota U341F gearbox

- Under active driving the lockup clutch wears out and this debris clogs the solenoids;
- And if you drive for a long time with a worn clutch, the oil pump bushing will be destroyed;
- The weak point of all U-series automatic transmissions is the Teflon rings in the rear cover;
- After 200,000 km they often wear out and the oil pressure in the system drops;
- This gearbox also dislikes frequent hard starts, as the planetary gearsets may not hold up.
