Component Identification:
Location
Each shift group has its own shift pressure shift valve. The shift pressure shift valve 1-2/4-5 and 2-3 shift pressure shift valve are located in the valve housing of the shift plate. The 3-4 shift pressure shift valve is installed in the valve body of the shift plate.
Task
Each shift pressure shift valve assigns a corresponding shift pressure to an engaging shift element. At the same time the regulated overlap pressure is assigned by the regulating valve overlap pressure to the disengaging shift element.
Function
The shift pressure shift valve is applied with working pressure at the end face over the command valve when the multi-disk brake is engaged. During the shifting phase, its shifting state is maintained, by replacing the variable shift element pressure acting on the end face during the shifting phase, with a corresponding constant pressure.
When the multi-disk clutch is engaged, the end face of the shift pressure shift valve is unpressurized during the stationary and shift phases, so the shift state is also maintained during the shift phase.
