Disadvantages of the Chrysler 42RLE gearbox
- Under intense acceleration, the torque converter clutch in this transmission wears out quickly;
- If it’s not replaced promptly, the oil pump bushing will break and leak;
- Wear debris contaminates the solenoid block, which requires regular cleaning;
- The transmission also doesn’t tolerate slippage, which is where the planetary gear fails;
- Electrically, the input and output speed sensors often fail in the automatic transmission.
