Abstract
A shut off control system for the fluid activated clutches of a transmission is provided. The inventive control valve automatically shuts off hydraulic flow to the clutches whenever the engine of the vehicle is turned off. When the vehicle is restarted the clutch pedal must be depressed and released before fluid can again activate the clutches. With the inventive control system, the vehicle can be started in any gear but the vehicle will not move until the clutch pedal is depressed and released by the vehicle operator.
