General Information

WARNING: This page is about a different car, the 2018 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.

Transmission 

The "automatic transmission 09G" has 6 hydraulically control forward gears. By passing the torque converter slip, the 2nd, 3rd, 4th, 5th and 6th gears become mechanically driven gears when lock-up clutch is closed.

Torque Converter

The torque converter is equipped with a lock-up clutch. The lock-up clutch closes depending on load and speed. The 2nd, 3rd, 4th, 5th and 6th gears can be mechanically driven (without slip).

ATF 

(Automatic Transmission Fluid)

ATF is a permanent fill. ATF does not need to be changed during maintenance.

The ATF levels inside the planetary gear and inside the final drive are checked and filled at the same time.

Drained ATF must not be used to fill again.

CAUTION:

Be very careful when handling transmission fluid. Dispose of drained transmission fluid correctly.

To drain, the rising tube is removed.

The height of this rising tube corresponds to the height of the ATF level.

Use only ATF available as a replacement part in the automatic transmission 09G. Using other fluids can lead to function problems or can even cause transmission failure. For the correct ATF part number. Refer to the Vehicle Diagnostic Tester.
