Technical issues and repair guidelines
The repair kit of gaskets and seals is always ordered with filters for reassembly procedure. It is usually ordered for changing teflon rings which must be changed to save friction components and the pump with solenoids. If the car is used with worn out teflon rings, then the friction elements get burnt and the rubber seals get harder because of the temperature.The overhaul is always accompanied by the replacement of burnt frictions and steel disks for K1, K2, B1 clutches. The reason is usually related to clogged valve body, solenoids, and seals. It is expressed in slippage of clutches under load or delays with shifting of gears.
The most problematic components of 09D:
- The main problem of 09D installed in Volkswagen is related to clogging and breakdown of the hydraulic clutch plate with solenoids caused by ATF overheating and burning of the hydraulic clutch friction lining.
- The torque converter is usually handed in for repair in order to replace worn-out clutch lock-up.
- The wiring of solenoids often causes some malfunction. Older transmissions are provided with external fine filter.
- Valve bodies for Tuareg are often handed in for repair.
For these transmissions it is recommended to take measures on improving the transmission cooling system, for example, by installing an additional radiator. It is also advised to check the ATF condition and change it as soon as it gets darker and loses transparency.
