Disadvantages of the Jatco RE4F04B gearbox
- Dust from worn torque converter lockup clutch gets into the oil;
- Dirty lubricant spreads throughout the system, clogging the solenoids of the automatic transmission’s valve body;
- Strong jolts or jerks, as well as vibrations in the transmission, appear;
- This usually causes the oil pump seals to break and lubricant leaks to begin;
- As a result of oil starvation, the planetary gear quickly wears out.
