A shift control system for vehicle includes a transmission that performs an upshift based on an accelerator opening, comprising: a detector that detects a longitudinal acceleration the vehicle, a calculator that calculates a change amount per unit time of the accelerator opening, and a controller that controls the transmission. The controller repeatedly executes upshift to reduce a speed ratio of the transmission based on a second condition that determines a shift timing of the upshift, upon satisfaction of a first condition. The first condition is satisfied if the acceleration increasing the vehicle speed is greater than or equal to a predetermined first threshold value, the change amount is in a stable state falling within a certain range, and a time period that the change amount keeps falling within the certain range has exceeded a second threshold value.
