A control method for an automatic transmission in which a starting gear shift stage is attained by fastening a predetermined brake element and a predetermined clutch element includes a step of supplying, when a command, which is for fastening the predetermined brake element and the predetermined clutch element that is to be fastened to input output rotation on an engine side to a transmission mechanism, and which is also for attaining the starting gear shift stage is detected, hydraulic pressure to the clutch element and then fastening the clutch element, and a step of supplying, after the step, the hydraulic pressure to the brake element to start the fastening of the brake element and controlling rotation, which is input to the transmission mechanism, to a target number of rotations. It is possible to satisfactorily attain the starting gear shift stage without a shock while dispensing with a one-way clutch.
