Abstract
A transmission control system of an automotive vehicle with a continuously variable automatic transmission, comprises an electronic transmission control unit which detects an acceleration of a drive wheel of the vehicle, and compares the acceleration of the drive wheel to a predetermined acceleration value. The control unit operates to inhibit only the upshifting action by preventing a speed ratio of the continuously variable automatic transmission from being upshifted toward a speed ratio less than a predetermined upshift limiting threshold.
