A control system (44) for a clutch (18) of a manual transmission (16) in a vehicle (10) having an ECU (22), an engine (14), a pedal (26) having a sensor (42), a slave (34) in fluid communication with a master (36); and at least one input (24). The control system (44) includes a pump (50), a valve (52) in fluid communication with the slave (34) and pump (50), and a controller (46) responsive to the ECU (22) and operable in a plurality of modes for selectively cooperating with the pedal (26) to actuate the slave (34) and modulate the clutch (18) under predetermined engine (14) and vehicle (10) operating conditions. The controller (46) is movable between modes in response to signals from the ECU (22) representing predetermined changes in one or more of: engine speed, engine load, vehicle speed, transmission gear, pedal position, or input state.
