A hybrid transmission includes a gearing mechanism and a V-belt type continuously variable transmission mechanism, a shift command valve, a shift control valve, and a high clutch. The continuously variable transmission mechanism has a driver pulley connected to receive a hydraulic fluid pressure generated by the shift control valve. A neutral valve is fluidly disposed between the high clutch and the shift control valve and has a drain port. The neutral valve takes a predetermined position upon the shift command valve assuming an overstroke range position to drain the high clutch via the drain port thereof, causing the high clutch to be released quickly. The shift command valve assumes the overstroke range position upon kickdown operation, for example. Thus, improved kickdown operation is provided owing to the quick release of the high clutch.
