Approximately at a completion timing of a rotation speed change, torque down of an engine is started by an engine torque variation control means C, and meanwhile when it is decided by a determining means D that a given time starting from the starting of the torque down passes, return of engine torque is started. This constitution reduces the generation of a speed change shock during down shift, and provides speed change transient characteristics by which a speed change time can be shortened.
