Abstract
A shift control device for establishing a desired gear stage promptly while reducing a shock, during propulsion while disengaging all of engagement devices of a transmission. The shift control system compares a target stage set based on an operating data to an interim stage set based on the operating data immediately before the target stage is set. If the target stage is lower than the initial stage the engagement devices are engaged to establish the target stage without establishing the initial stage.
