Abstract: The present invention relates to a method for controlling a reverse shift restriction in a drive "D" range of a vehicle having an automatic transmission. The method for controlling a reverse shift restriction in a drive "D" range of a vehicle's automatic transmission, comprising the steps of generating a frequency signal representative of the vehicle speed and direction. Next, determination of whether creeping is occurring is necessary. The automatic transmission is controlled based on said determination said frequency signal.

Abstract: A method for controlling a damper clutch when a vehicle having an automatic transmission requires increased power. For example, when accelerating while driving uphill, the present invention disengages a damper clutch. This advantage is obtained by identifying a power increase region on the damper clutch engaged region of operation such that the damper clutch is disengaged. The method for controlling the damper clutch includes a step of generating engine signal indicative of engine rpms and throttle position. A control signal is developing such that control of the damper clutch is based upon the generated engine signals.
