Abstract
A transmission control unit predicts a next gear position when a predetermined gear position is achieved. In accordance with a result of the prediction, the transmission control unit operates a predetermined synchromesh to execute a standby control (pre-shift control). In the standby control, a transmission input shaft connected to a friction transfer mechanism not used for achieving a current gear position and a transmission output shaft are connected to each other via a predetermined gear train, and made standby. The transmission control unit makes different from each other an engagement load of the synchromesh when a connection of the synchromesh is done in accordance with the prediction result and an engagement load of the synchromesh when a connection of the synchromesh is done in accordance with the other condition different from the prediction result.
