Disadvantages of the ZF 8DT-80 gearbox
- This transmission hasn’t been around very long, so there aren’t any detailed breakdown statistics yet;
- In the early years of production, owners complained about jolts, but firmware updates have fixed this;
- If the transmission oil isn’t updated, the valve body will need to be cleaned at 100,000 km;
- With excessively aggressive driving, the clutches can wear out critically by 50,000 km;
- The high cost of a new transmission is also worth noting.
