ABSTRACT:
In an automatic transmission of a motor vehicle, a torque of a transmission output member is detected, after the detected torque has dropped at a rate greater than a predetermined value after generation of a gear shifting command signal, a length of time elapsed thereafter is measured, a pressurized hydraulic fluid is modified as a predetermined function of the length of time measured, and a hydraulically actuable coupling is actuated by the modified pressurized hydraulic fluid.
