ABSTRACT:
An ECU executes a program including the steps of: starting disengagement of a C2clutch and a B1brake when downshifting a transmission implementing gears in accordance with combinations of engaged clutches and brakes from sixth gear to third gear, or disengagement of the C2clutch and a B3brake when downshifting from fifth gear to second gear; when at least one of the C2clutch and the B1brake, or at least one of the C2clutch and the B3brake, is completely disengaged, starting engagement of a C1clutch and the B3brake when downshifting from sixth gear to third gear, or engagement of the C1clutch and the B1brake when downshifting from fifth gear to second gear.
