Abstract
A transmission, preferably for driving a motor vehicle, includes a multi-gear main transmission and a range group, that is connected downstream from the main transmission and comprises an input shaft and an epicyclic gear system. The epicyclic gear system comprises elements in the form at least of a central gearwheel and a planetary carrier. Furthermore, the transmission comprises a first connection for driving one of the elements of the epicyclic gear system by way of the input shaft of the range group and a variator, as well as a second connection that can be engaged with the first connection for driving a further element of the elements of the epicyclic gear system. When the second connection is engaged, the input shaft of the range group drives the variator and a drive output of the variator drives the further element of the epicyclic gear system.
