Main shaft has extension protruding into intermediate chamber of housing disposed between cross walls which separate said chamber from clutch and gearbox. Extension carries gear wheels meshing alternately with the gears connected to countershaft, thus providing for step-up and step-down ranges in the power transmission. Smaller-diameter gear on countershaft meshes with gear secured on output shaft. Countershaft extension is supported by bearing in housing wall and its outside diameter is smaller than the diameter of the part of countershaft disposed in chamber accommodating gearbox gears.
