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.

A method for preventing overheating of a clutch for a vehicle may include determining, by a controller, whether a state of the vehicle satisfies a hill hold condition; acquiring, by the controller, a temperature of a clutch between an engine and a transmission when the hill hold condition is satisfied; applying, by the controller, a first torque having a predetermined square wave shape to the clutch when the temperature of the clutch reaches a first temperature; and applying, by the controller, a second torque having a predetermined sine wave shape to the clutch when the temperature of the clutch reaches a second temperature higher than the first temperature.
