Abstract

A twin-clutch transmission having the driving gear wheels of adjacent gears on different transmission input shafts permits skipping one gear stage while shifting gears, i.e. shifting between gears whose driving gear wheels are on the same transmission input shaft, by using an auxiliary gear on the other transmission input shaft to supply a filler torque while shifting between the initial gear and a selected gear.
