Function of gear shift - GF27.60-P-2000PM

TRANSMISSION 722.6 in MODEL 203 (except 203.02 /05 /076 /22 /25 /276) as of 24.4.04 except CODE (428a) Steering wheel shift buttons 

On the automatic transmission 722.6 the electrohydraulic control unit converts the electrical signals coming from the electronic transmission control (ETC) into hydraulic signals

Faults occurring in the ETC control unit (N15/3) are handled by the limp-home system. This is designed to allow the driver to reach a service outlet even under extreme conditions.

Selector lever positions "P", "R", "N" and "D" are transmitted by the electronic selector lever module control unit (N15/5) on the Controller Area Network bus class C (engine compartment) (CAN-C) and in parallel with this passed on to the range selector lever at the transmission end by means of a shift rod. Via touching or holding the selector lever towards "+" or "-" the shift range is preselected and displayed in the instrument cluster (A1) until an upshift of the transmission is possible.
