Beschreibung
Zusammenfassung:	The invention relates to an automatic gearbox for motor vehicles, comprising an electronic drive control device and an electric gear range selecting element. In case the drive control device fails such that the gears can no longer be changed when the gear range selecting element is actuated with a view to changing gear range, and if the gears which can be changed by means of the gear range selecting element can be identified, the driver receives a corresponding optical, acoustic and/or haptic feedback signal which indicates said failure. In case the gera rage selecting element fails in such a way that the gear ranges adjustable by means of said gear range selecting element can no longer be identified, a corresponding optical, acoustic and/or haptic feedback signal which indicates said failure is immediately transmitted to the driver.
