Disadvantages of the ZF 6HP32 gearbox
- In the early years, mechatronics often failed and dealers replaced them under warranty;
- This automatic transmission is installed with particularly powerful engines and the torque converter clutch wears out quickly;
- The solenoids of the valve body become clogged with wear products and the gearbox begins to push;
- If you do not pay attention, vibrations from the shaft will destroy the oil pump bearing;
- A known weak point of all gearboxes in this series are short-lived bushings.
