Abstract: The invention relates to a gearshifting device (1), which is intended for a transmission and comprises a selector lever (2) that can be moved in such a manner that different shift positions (P, R, N, D, S, M+, M?) can be selected in at least two gearshift gates (3, 4) and that it is possible to shift between one of the gearshift gates (3, 4) and the at least one other gearshift gate (4, 3), and comprises at least one lock (5), which is used to block the traversing path of the selector lever (2) with respect to one of the gearshift gates (3, 4), in order to shift from one of the shift positions (P, R, N, D, S) into another of the shift positions (P, R, N, D, S).
