Abstract

A transmission for vehicle includes: a transmission mechanism including a first engagement device configured to block/allow power transmission between an engine and a first input shaft of a first gear stage group, and a second engagement device configured to block/allow power transmission between the engine and a second input shaft of a second gear stage group; a differential mechanism; and a control device. The first gear stage group includes a starting stage used at a time the vehicle starts traveling, and the control device performs travel starting control to start traveling of the vehicle by: putting the second engagement device into an engaged state while the engine is operating before the vehicle starts traveling; and putting the second engagement device into a disengaged state, thereafter controlling rotation of a rotational machine and putting the first engagement device into an engaged state at the time the vehicle starts traveling.
