Abstract
A method is provided for controlling an automatic transmission. The method initially determines if a kick down gear change is required. If so, the method determines if the throttle rate is increasing. If the throttle rate is increasing, the method determines if the throttle rate is less than a pre-selected threshold. If the throttle rate is greater than or equal to the pre-selected threshold, the kick down gear change is performed at an aggressive rate. However, if the throttle rate is less than the pre-selected threshold, the kick down gear change is performed at a slower rate.
