General Information
Transmission
The "automatic transmission 09G" has six hydraulically-controlled forward gears. By passing the torque converter slip, 2nd, 3rd, 4th, 5th and 6th gears become mechanically driven gears if lock-up clutch is closed.
Torque Converter
The torque converter is equipped with a slip controlled torque converter 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 filling. As far as Maintenance is concerned, the ATF does not need to be replaced.
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.
Be very careful when working with transmission fluid. Dispose of drained transmission fluid correctly.
To drain, 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 oils can lead to function problems or can even cause the transmission to fail, ATF part number.
