Abstract
Abstract In an automatic gear-shifting mechanism for a shiftable transmission of motor vehicles, with two adjusting mechanisms which are each vertically pivotal about a vertical bearing and which displace a shifting lever of the gear-shifting transmission into the gear positions according to a test program, two freely movable horizontal bearings for the horizontal movement of the shifting lever are coordinated to the adjusting mechanisms and the adjusting mechanisms are constructed as electric stepping motors. The testing program is obtained with the use of the respective gear-shifting transmission.
