Abstract
A forward clutch choke ( ) having an internal long narrow path is provided in an oil path which feeds a clutch pressure (P ) to an oil chamber ( ) of a forward clutch mechanism ( ). The choke restricts a flow of the hydraulic oil into the oil chamber at a low temperature where the viscosity of the hydraulic oil is high to thereby increase a time required for the oil chamber to be filled with the oil, which prevents the clutch mechanism ( ) from being engaged tightly in a short time to thereby prevent an instantaneous rise in the output shaft torque. Since the viscosity of the hydraulic oil is low at normal temperature and the choke functions as an orifice, the clutch mechanism is smoothly engaged tightly based on the operation of an accumulator concerned (FIG. ).
