Location
Each shift group has its own command valve. The command valve 1-2/4-5 and 2-3 command valve are installed in the valve housing of the shift plate. The 3-4 command valve is installed in the valve body of the shift plate.

Task
The command valves switch the shift groups from the steady-state phase into the shift phase and back.








Function
When the end face is unpressurized (stationary phase) the working pressure is routed to the shift element operated.

If shift valve pressure is applied to the end face of the command valve (switching phase), then the shift pressure is shifted through to the engaged element and the overlap pressure to the disengaged element.
