Abstract
The present invention provides a device for prohibiting upshift on an automatic transmission which has a controller adapted to select a gear ratio of the automatic transmission. The controller receives an output speed signal representative of a speed of the vehicle and throttle signal representative of a throttle position. Based on this information, the controller prohibits the automatic transmission from upshifting when the throttle position changes from a substantially open position to a substantially closed position at a rapid rate.
