Abstract

PURPOSE:To promote the reduction of a shift shock by changing a pressure of oil in a control chamber by a solenoid valve through a control circuit and decreasing an output pressure of a regulator valve when a shift is performed with a fine throttle opening. CONSTITUTION:When a shift of N-D or N-R is performed with a fine throttle opening, an electronic control unit 28 generates an electric current of predetermined duty ratio actuating a solenoid valve 11, controlling a pressure of oil in a control chamber 36 and decreasing an output pressure of a regulator valve 4 by signals from a throttle opening sensor 30 and a shift position sensor 33. In this way, an engaging shock is relaxed. While in the time of speed change shift with an accelerator off, in a predetermined range, generating a predetermined solenoid current when a car speed reaches the speed change car speed, the solenoid valve 11 is actuated decreasing the output pressure and relaxing a speed change shock in the time with the accelerator off. Thus relaxing the shift shock, a control feeling improves.
