1. An automatic gear-shifting arrangement for a gear-shifting transmission of motor vehicles, comprising:
- two adjusting means each for displacing a shifting lever of the transmission into the gear positions according to a test program;
each adjusting means includes;
an actuating rod connected at a first end to said shifting lever and having a second end,an electric stepping motor means having an axis of rotation,vertical bearing means for vertically pivoting said motor means about a horizontal axis, andhorizontal bearing means for horizontally pivoting said second end of said actuating rod relative to said motor means about a vertical axis to coordinate the movement of the two adjusting means.

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.
