An automatic transmission includes a first frictional engagement element (a low clutch 40), a second frictional engagement element (an L/R brake 60), two hydraulic chambers (a gap adjustment chamber 64 and a pressure chamber 65) provided in the second frictional engagement element, a first hydraulic pressure generator 101 (an electric pump 101) generating a hydraulic pressure during an automatic stop of the engine, and a control unit (a control unit 200) controlling the hydraulic pressure in the first and second frictional engagement elements. The control unit supplies the hydraulic pressure generated by the first hydraulic pressure generator to the first frictional engagement element and one of the two hydraulic chambers of the second frictional engagement element when the automatic transmission is in the non-traveling range and the engine has been automatically stopped.
