Disadvantages of the Toyota A750F gearbox
- This is a strong gearbox and problems arise only when used too hard.
- The torque converter lock-up clutch wears out first, contaminating the oil.
- Then the dirty lubricant damages the solenoids and corrodes the channels in the valve body.
- When the torque converter clutch wears out, vibrations appear and the oil pump bushing breaks.
- Next, a strong oil leak usually appears, which is quite dangerous for the transmission.
