Abstract

A vehicle transmission includes a transmission input and output along with a main shaft and a countershaft that create a plurality of transmission ratios for providing different gears when combined. The vehicle transmission also includes a range change transmission. The vehicle transmission also has, in the direction of the propulsion power flow from the transmission input to the transmission output, a performance interface downstream of the countershaft and upstream of the range change transmission for connecting an electric motor.
