Abstract

A vehicle according to the present disclosure includes a shift-by-wire transmission, a pressure source configured to selectively provide hydraulic pressure in the absence of engine power, an internal combustion engine, and a controller. The shift-by-wire transmission includes a hydraulic actuator, and the electric pump is in fluid communication with the actuator. The controller is configured to, in response to a driver input and the engine being off, control the pressure source to provide hydraulic pressure to the hydraulic actuator.
