Abstract
A control device executes, when a jump-down shifting is executed, shifting control in which, after engaging elements establishing a pre-shifting gear position are released, an intermediate gear position that is a gear position between the pre-shifting gear position and a post-shifting gear position is established, and after the intermediate gear position is established, the post-shifting gear position is established. When an engaging element able to reduce a rotation speed difference between two rotating bodies connected by engaging elements establishing the intermediate gear position is regarded as a speed difference reducing element, the control device executes a pre-engaging process for generating a torque capacity in the speed difference reducing element while the shifting control is being executed and before establishing the intermediate gear position.
