In a vehicle automatic transmission having structure in which an output-side rotating element is provided between a speed increasing-side rotating element that is connected to an engine via input clutch and increased rotation speed during downshift into a predetermined speed, and a speed reducing-side rotating element that is reduced in rotation speed by a second engagement apparatus being engaged during the downshift, in an alignment graph, the first engagement apparatus is engaged when, or after, the second engagement apparatus is engaged at the time of the downshift into the predetermined speed. As a result, the rotation speed of the speed reducing-side rotating element is reduced first by the engagement of the second engagement apparatus, which causes driving force to act on the output-side rotating element in a direction that reduces the rotating speed thereof. As a result, forward driving force is prevented from being generated by the output-side rotating element.
