Disadvantages of the TB-50LS gearbox
- This is a fairly reliable gearbox and problems arise only at high mileage;
- First, the torque converter lock-up clutch wears out, contaminating the oil;
- And then dirty oil damages the solenoids and corrodes the valve body channels;
- Worn torque converter clutch causes vibrations that break the oil pump bushing;
- Then lubricant leaks appear, and a significant drop in level is dangerous for the transmission.
