A method for operating a transmission device for a motor vehicle. A drive gear is selected from a drive gear set and set on a transmission and upon going above a rotational speed upper limit a drive gear with a larger gearing ratio and upon going below a rotational speed lower limit a drive gear with a smaller gearing ratio is selected from the drive gear set and set on the transmission. In a normal operating mode, the drive gear set corresponds to a normal operation drive gear set having a plurality of different drive gears, and the rotational speed upper limit corresponds to a normal operation rotational speed upper limit and the rotational speed lower limit corresponds to a normal operation rotational speed lower limit. In an alternative operating mode the drive gear set corresponds to an alternative operation drive gear set, having a smaller number of different drive gears than the normal operation drive gear set.

A method for operating a transmission device for a motor vehicle, wherein a drive gear is selected from a drive gear set and set on a transmission and upon going above a rotational speed upper limit a drive gear with a larger gearing ratio and upon going below a rotational speed lower limit a drive gear with a smaller gearing ratio is selected from the drive gear set and set on the transmission, comprising:
A transmission device for a motor vehicle, wherein the transmission device is designed to select a drive gear from a drive gear set and set it on a transmission and upon going above a rotational speed upper limit to select a drive gear with a larger gearing ratio and/or upon going below a rotational speed lower limit to select a drive gear with a smaller gearing ratio from the drive gear set and to set it on the transmission, wherein, in a normal operating mode, the drive gear set corresponds to a normal operation drive gear set having a plurality of different drive gears, and/or the rotational speed upper limit corresponds to a normal operation rotational speed upper limit and the rotational speed lower limit corresponds to a normal operation rotational speed lower limit, and in an alternative operating mode the drive gear set corresponds to an alternative operation drive gear set, having a smaller number of different drive gears than the normal operation drive gear set, and/or the rotational speed upper limit corresponds to an alternative operation rotational speed upper limit which is different from the normal operation rotational speed upper limit and the rotational speed lower limit corresponds to an alternative operation rotational speed lower limit which is different from the normal operation rotational speed lower limit.
