Disadvantages of the VW AQ450 gearbox
- This automatic transmission is installed with powerful units and the torque converter clutch wears out quickly.
- Then the solenoids become contaminated with wear products and the gearbox begins to push.
- It is important to monitor the cooling of the automatic transmission; its heat exchanger may become clogged by 100,000 km.
- Overheating destroys the Teflon rings and the lubricant pressure in the system drops.
- And this leads to rapid wear of the clutches in the packages and very expensive repairs.
