Abstract

A selector device for an automated or automatic transmission, in particular of a motor vehicle, has a selector lever which is adjustable in an automatic selector gate to switch between automatic operating positions and can be moved via a transverse gate into a tip-action selector gate in which it is adjustable to shift between transmission gears. Here, the selector lever has one stable operating position in the tip-action selector gate, to which stable operating position the selector lever automatically returns from all the labile positions of the three gates. To increase operating comfort and to increase operational safety, a transmission controller is configured such that, after an automatic operating position is selected, it only switches to the selected automatic operating state when the selector lever resumes its stable operating position.
