Location
A command valve belongs to each shift group. The 1 - 2 or 4 - 5 command valve and 2 - 3 command valve are installed in the valve body of the valve body assembly. The 3-4 command valve is installed in the shift plate valve body.

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 (shift phase), then shift pressure is transmitted to the engaging actuator and overlap pressure is transmitted to the disengaging actuator.
