Zusammenfassung:A gear shifting assembly for change-speed transmissions of the type having several shifting members which are actuatable to thereby set the transmission to a desired speed position employs two fluid-operated motors the first of which can move a displacing member into register with a selected shifting member and the second of which thereupon actuates the selected shifting member by way of the displacing member. The admission of a pressurized fluid to and the evacuation of fluid from the cylinders of the motors is regulated by a system of valves which are operated by pressurized fluid or by an electronic control unit.
