Abstract: PURPOSE:To eliminate rapid engine brake action due to deceleration so as to reduce a speed change shock by providing a hydraulic clutch boost delay means for controlling a hydraulic clutch so as to increase a time before it is connected when a speed change is shifted to a low speed side. CONSTITUTION:When a power shift transmission is shift-operated by an opera tor, a hydraulic clutch 11, to be connected with that time, is cut off, while a shift detecting means 5b detects whether a speed change is shifted to a high speed side or a low speed side.
