Abstract

A shifting device (4) is provided for an automatic transmission and has an additional manual shifting function. The device includes a selector lever (6), which is mounted pivotably on a gear shift lever (10) such that different, automatically shiftable gears can be preset in a first shift gate (1) and individual, manually shiftable gears can be preset in a second shift gate (2). A housing (5) is provided, in which the gear shift gate (10) is mounted with the selector lever (6) pivotably in such a way that shifting between a predetermined gear (“D”) of the first shift gate (1) and a neutral position (“M”) of the second shift gate (2) is made possible. The further shifting from the predetermined gear (“D”) of the first shift gate (1) into at least one other gear (“3”) of the first shift gate is prevented by a lock, which is overcome by the actuation of an actuating element. The lock is formed by a stop (15) of the housing (5) and an intermediate piece (18) arranged on the gear shift gate (10) between the selector lever (6) and the stop (15).
