Disadvantages of the Ford 6F15 gearbox
- Early-generation automatic transmissions suffered from delays when shifting in first gear;
- Most owners were helped by a reflash, but some also had to replace the valve body;
- The oil in this transmission also gets dirty very quickly, which also leads to jerking;
- To extend the life of the transmission, we recommend changing the lubricant every 30,000 km;
- The differential is also considered a weak point; it does not tolerate prolonged slippage.
