Abstract: A transmission device with at least two multi-gear transmission groups. Torque is introduced via a input shaft into the transmission groups and into the other transmission group via a main shaft. The input shaft is directly connected with the main shaft via a shifting element during a gearshift to achieve an intermediate gear. When the intermediate gear is engaged, torque passes to the shafts connected to each other via the shifting element. A method for operating transmission, during the gearshift, includes introducing torque from the electric machine to the shafts connected via the shifting element and adjusting the rotational speed of the input shaft to the rotational speed of the target gear. A further shifting element is engaged in the first transmission group, the shifting element is disengaged, and torque of the electric machine is reduced, once the rotational speeds of the input shaft and the target gear match one another.
