Date Nov. 20, 1986.A vehicle driven by a super charged engine has a gear transmission that is automatically shifted between drive ratios under the joint control of vehicle speed and engine load demand, modified by a loading signal pressure derived from the engine carburetor to correctively influence the change in drive ratio so as to accommodate a super charged type of engine. Such loading signal pressure is applied to a shift valve of the transmission control system independently of control pressure reflecting vehicle speed and engine load demand in order to correctively modify the pressure control exercised during the drive ratio change interval.
