Disadvantages of the ZF 8DT-80 gearbox
- In the first years of production, owners complained about shocks, but firmware updates fixed everything.
- If you do not update the oil in the gearbox, then the valve body will have to be cleaned at 100,000 km.
- With excessively active driving, clutches can become critically worn out by 50,000 km.
- It is worth noting the high cost of a new gearbox.
