PROBLEM TO BE SOLVED: To provide a dual clutch automatic transmission capable of reducing time required for upshifting and yet suppressing the vibration of a vehicle accompanying the upshifting while suppressing an increase in the number of components.SOLUTION: At a time of upshifting for shifting a first gear position to a second gear position and switching over switching means S1 from a first shift position to a second shift position, a duel-clutch automatic transmission 200 controls the switching means S1 to a neutral shift position, controls a clutch C1 (C2) that is not engaged at a first gear position into a half clutch state to reduce a rotating speed of a drive source 2, and controls one clutch C2 (C1) into an engaged state, the other clutch C1 (C2) into a disengaged state, and the switching means S1 to a second shift position. |
