Activation Sequence
The selector valve (Fig. 20) opens the shift pres-
sure (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 multiple-disc
holding clutch B2 begins to close.
