Abstract
In a group transmission having a number of countershafts, wherein three input constants are provided on a transmission input shaft for driving a countershaft such that the group transmission is of very short construction, the transmission input shaft is connectable to an intermediate shaft for direct power transmission, with the countershaft being disconnectable in the direct gear in order to avoid drag losses.
