Abstract
A dual clutch automatic transmission includes a one-way clutch provided in a driving force transmission path that establishes a first certain gear ratio in a first set of gear ratios. A driving transmission direction of the one-way clutch is set such that a rotation inputted from a wheel side to an output member in a predetermined rotational direction is transmitted to the input shaft. The predetermined rotational direction corresponds to a backward movement of a vehicle. If an off-gear operation cannot be performed for a transmission gear with interlock, the driving force of the driving source is input to the input shaft to enable the off-gear operation.
