A shift control system includes a controller that controls a transmission and a hydraulic controller. During an inertia phase where an input speed of the transmission changes toward a synchronous speed in a gear stage after a shift, the controller sets an oil pressure of a specific frictional engagement of a plurality of frictional engagement devices to an oil pressure that, at a time of the shift, exceeds a first oil pressure to set a transmission torque capacity equal to a first drive torque applied to the specific frictional engagement device of a drive torque outputted from a prime mover, but is less than a second oil pressure to set a transmission torque capacity equal to a second drive torque which is the first drive torque to which has been added an inertia torque generated by inertia on a prime mover side accompanying a change in speed ratio.
