ABSTRACT:
A selector transmission for a motor vehicle in which two transmission shift positions G1, G2; G3, G4; G5, G6situated in a shifting gate55of an H or multi-H shifting gate51within a transmission1can be respectively shifted via two different shifting sets29, 30, 31, 32. The transmission1has one transmission input shaft5, two countershafts15, 16, one reverse gear shaft22and one transmission output shaft28available. The fixed and idler gears of each ratio step are positioned on the transmission shafts so that, departing from a single starting and separating clutch4of the transmission, the transmission gears are disposed in a sequence G2and RG, G4and G6, G3, G1, G5. Between the gear wheels of the second and of the fourth gear, of the third and first gear and between those of the reverse gear and the sixth gear, the shifting sets29, 30, 31, 32are, in addition, located upon the countershafts15, 16with which each idler gear can be non-rotatably connected with respectively associated countershafts. Such a transmission is shiftable with a shifting device50having H or multi-H shifting gates51and comprises one mechanical conversion device which converts a shifting movement from one gear position to the next gear position G1–G2; G3–G4; G5–G6in one shifting gate55into actuation movements for two shifting sets29, 30, 31, 32in the transmission1.
