Shift pressure, function - GF27.60-P-3015GZ

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 164.1/8, 204.0, 216, 221, 251.0/1 up to Model Year 8 

The shift pressure (pressure in the multi-disk clutch or in multi-disk brake) is derived from the working pressure. The respective control solenoid valve influences the position of the associated regulating valve. In turn the position influences the pressure prevailing in the multi-disk brake or in multi-disk clutch.

The pressure thus depends on the geometry of the respective regulating valve.
