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. 3-14 A Y6 Y5 B Y4 Y1 Y2 Y3 SECTION A-A
