WARNING: This page is about a different car, the 2011 Mercedes-Benz C300, 2010 Mercedes-Benz C300, 2009 Mercedes-Benz C300, and 2008 Mercedes-Benz C300. However, it is still accessible from the selected car via links, so may be relevant.

TRANSMISSION 722.9 in MODEL 204.0 up to Model Year 8

The electrohydraulic controller unit converts electrical signals going out from the fully integrated transmission control (VGS) into hydraulic signals. Faults occurring in the VGS are covered by the limp-home mode. The limp-home strategy is designed so that the driver can still reach a Mercedes-Benz service operation under extreme conditions.

The gear selector switch positions "P", "R", "N" and "D" are transferred by the steering column module control unit (N80) to the chassis CAN. The ME-SFI [ME] control unit (N3/10) conveys the information on the drive train CAN. The fully integrated transmission control unit (Y3/8n4) passes on the gear selector switch positions to the electronic selector lever module control unit (N15/5) taking various information into consideration.

The electronic selector lever module control unit changes the position of the selector range lever, which is transmitted mechanically to the selection range sensor (Y3/8s1).

The shift range up to which the transmission can be upshifted is preselected via the steering wheel downshift button (S110/1) (with code (428) Steering wheel shift buttons) and via the steering wheel upshift button (S111/1) (with code (428) Steering wheel shift buttons). The shift range is displayed in the instrument cluster (A1).
