To supply a clutch control system for a transmission capable of appropriately performing preparations for driving of a plurality of hydraulic clutches driven by oil pressures supplied from a hydraulic pump, at an engine starting time. A clutch control system for a twin-clutch type automatic/manual transmission (AMT) includes the hydraulic pump for driving a first clutch (CL1) and a second clutch (CL2), oil passages for transmitting oil pressures respectively to CL1 and CL2, and an AMT control unit for controlling the supply of oil pressures into the oil passages. Upon detection of an engine starting operation, the AMT control unit performs an initial preparatory operation in which the oil pressures are supplied into the oil passages at different timings so as to fill up the oil passages with a working oil, thereby completing the preparations for driving of the clutches. When such a setting is made that the oil pressure is supplied into the oil passage after a predetermined oil pressure Pc is generated in the oil passage, the period of time taken for a first speed gear to become usable is shortened, whereby a swift vehicle starting after the starting of the engine can be achieved.
