Command Valve

Location/Task/Function

Component Illustration:

Location
Each shift group possesses one command valve. The 1-2 / 4-5 and 2-3 command valves are installed in the shift valve housing; the 3-4 command valve is installed in the valve housing.

Task
The command valve switches the shift group from the stationary phase to the shift phase and back again.

Function
When the end face is unpressurized (stationary phase), the working pressure is directed to the actuated shift element. If the end face of the command valve is subjected to the shift valve pressure (p-SV) (shift phase), then the shift pressure is switched to the activating element and the overlap pressure is switched to the deactivating element.
