Abstract
There is provided a control device for an automatic transmission configured to automatically shift a transmission of a driving force of a motor in response to a driving state. The automatic transmission includes a synchromesh mechanism configured to couple gear pairs and a rotary shaft to transmit the driving force of the motor to the gear pairs and a switching apparatus configured to switch a coupling state of the gear pairs and the rotary shaft. A preload control unit is configured to operate the switching apparatus to apply a preload to the synchromesh mechanism when a shift transmission request is detected. A shift control unit is configured to operate the switching apparatus to apply a shift load greater than the preload to the synchromesh mechanism after the preload is applied to the synchromesh mechanism.
