Pressure Regulation

With the manual valve in the reverse position, line pressure is directed into the reverse fluid circuit.

Reverse fluid is routed through the reverse lockout valve into the reverse lockout fluid circuit.

Reverse clutch fluid at the line boost valve boosts line pressure for the additional torque requirements in Reverse. Throttle signal fluid pressure from the pressure control - PC solenoid acting on the line boost valve also helps determine line pressure in Reverse depending on throttle position and other TCM input signals.
