Disadvantages of the Ford A4LD gearbox
- This automatic transmission works well with engines up to 3 liters, but not so well with more powerful ones;
- Most often, the brake bands break, and the pistons or overdrive drum burst;
- Due to regular overheating, the bushings and plastic washers become unusable;
- Remaining problems with the automatic transmission are related to solenoids becoming contaminated with wear debris.
