Claims

[Scope of utility model registration request]

A hydraulic clutch that is assembled to the torque converter and connected to the input shaft of the gear transmission, which can directly connect the output shaft of the torque converter and the output shaft of the engine, and hydraulic pressure that supplies and discharges pressure oil to and from the hydraulic clutch. an oil temperature detector for detecting the oil temperature of automatic transmission oil; a gear position determining means for detecting the gear position of the gear transmission; and a control device that connects the hydraulic clutch only when the gear position is on the high speed side or when the automatic transmission oil is at a high temperature, and directly connects the output shaft of the torque converter and the output shaft of the engine. Automatic transmission for vehicles.
