Abstract: A fluid control system for actuating a master clutch has a variable pressure regulator valve which operates in response to engine speed and engine load. The variable fluid pressure is delivered to a clutch actuating piston to regulate the magnitude of actuating pressure for operating the clutch. Fluid directed away from the clutch actuating piston is used to provide cooling for the clutch. A clutch dump valve is incorporated in the control system to completely disengage the clutch making gear ratio shifts. To alleviate clutch drag, the controls are such as to also dump the clutch lube oil when the clutch is in neutral and when the clutch is disengaged during transient transmission ratio shifts.
