Disadvantages of the Opel AF13 gearbox
- This is a reliable Japanese automatic transmission, and all its problems stem from age and skimping on oil;
- Even the torque converter lockup clutch wears out only after 200,000-250,000 km;
- When the torque converter clutch wears critically, its seal begins to leak;
- A significant drop in oil level is dangerous for the planetary gear, which is rather weak;
- Also, the input and output speed sensors of this series of automatic transmissions regularly fail.
