Abstract
A clutch operation control system for a fluid torque converter of a vehicular transmission in which the fluid torque converter is equipped with a clutch for mechanically connecting the input side and output side of said torque converter. The clutch has its clutch plate supplied at its one side with oil pressure in a control chamber to release the clutch and at its other side with the torque converter oil pressure in said fluid torque converter for operating the clutch by the differential pressure across the clutch plate. An oil line leading to the control chamber is connected at a vehicular speed equal to or higher than a predetermined level to an oil drain port by means of a control valve to operate the clutch with an engaging force of the torque converter pressure. The clutch plate has an orifice for providing communication between the two sides of said clutch plate. The control valve is formed with a throttle portion for throttling the communication passage between the oil line to the control chamber and said drain port in a relatively low vehicular speed range equal to or higher than said predetermined level for allowing some slippage of the clutch.
