Abstract:
A select control device for an automatic transmission includes a select lever and a controller. The select lever is configured to select a range position in response to a select operation by a driver. The controller is configured to, when a first select operation from a first travel range position to a non-travel range position is performed, perform pressure release control that decreases at a prescribed descending gradient an engagement capacity of a starting clutch that is engaged in the first travel range position. The controller has a select hydraulic pressure control unit configured to continue the pressure release control during a second select operation from a second travel range position that is different from the first travel range position to the non-travel range position after the first select operation.
