Activation Sequence
The selector valve opens the shift pressure (p-S) feed connection from the ball valve (19) with the shift valve B2 (9). With the shift valve B2 (9) in the upper position, shift pressure (p-S) travels behind the piston B2 (5) and simultaneously to the opposing face of the piston B2 (6). The multi-disc holding clutch B2 begins to close.
The pressure on the opposing face of the piston B2 (6) ensures a soft activation of the multi-disc holding clutch B2.
