Abstract
An automatic transmission control device is configured to execute a first shifting between a pre-shifting gear position and an intermediate gear position, and a second shifting between the intermediate gear position and a post-shifting gear position such that each of the first and second shiftings is executed by releasing one of engagement devices and engaging one of the engagement devices, and is configured, upon transition from the first shifting to the second transition, to gradually changing an engagement torque of an engagement-maintained engagement device as one of the engagement devices which is engaged upon completion of the first shifting and is maintained in the engaged state during the second shifting, such that the engagement torque of the engagement-maintained engagement device is changed gradually from a required engagement torque required upon completion of the first shifting, to a required engagement torque which is required in the second shifting.
