摘要

According to the present invention, in order to effect a shockless shift in an automatic transmission of a vehicular power train, a servo activating hydraulic fluid pressure applied to a shifting friction unit is controlled in response to a predetermined variable other than an engine throttle opening which causes a change in engine output torque from a predetermined pattern of variation of the engine output torque against variation of the engine throttle opening.
