A position-feedback-control servomechanism (28) for shifting the transmission of a vehicle has a control algorithm that adjusts the loop gains (148, 156) in a proportional-integral-differential controller to compensate for manufacturing variations in the apparatus as well as for temperature changes and wear. The resulting control system moves the shifting servomechanism (28) into the selected positions accurately and as quickly as possible without permitting excessive overshooting (71) or resonance. <IMAGE> |
