The six clutches of the transmission are selected via the 6 proportional valves P1 to P6. The
proportional valve (pressure regulator unit) is composed of pressure regulator (e.g. Y1), follow-on
slide and vibration damper.
The control pressure of 9 bar for the actuation of the follow-on slides is created by the pressure
reducing valve. The pressure oil (16+2 bar) is directed via the follow-on slide to the respective
clutch.
