Abstract

In a method for shifting gears of an automatic transmission, in which a shift finger can be moved by a selective actuator along a selective path into various selective positions, out of which the shift finger can be moved via a shift actuator into different shift paths and the shift finger engages a gear each when it is moved into an end region of a shift path, the selective actuator is activated for verifying the correct function of the selective actuator and its connection to the shift finger prior to each engagement of a new gear within a shift path such that by approaching the edge of the shift gear the respective shift path is detected.
