Disadvantages of the VW ML450 gearbox
- This is a reliable and durable manual transmission, but it was installed with particularly powerful engines;
- Therefore, with vigorous driving, the synchronizers in the first gears wear out quickly;
- Frequent and abrupt starts will also require replacing the clutch every 50,000 km;
- At around 150,000 km, the dual-mass flywheel often needs replacing;
- Around 200,000 km, the shaft bearings may begin to hum, but this only occurs with vigorous driving.
