Disadvantages of the Ford AX4S gearbox
- This transmission is considered unreliable and is susceptible to overheating or intense acceleration;
- Typically, repairs are needed due to torn brake bands and burnt pistons;
- In more severe cases, cracked clutch drums must be replaced;
- The shift solenoid valves and main pressure solenoid don’t last long;
- A drop in oil pressure worsens the situation and increases wear on mechanical parts.
