The multi-speed transmission with one reverse and seven forward gears has input and output shafts, three planetary gear sets, six shafts and six shifting elements. The input shaft couples the sun gear of gear set (P2) and detachably couples shaft (5), which couples the carrier of gear set (P3), and detachably couples the housing and shaft (4). Shaft (4) couples the carrier of gear set (P2), detachably couples the housing via brake (04), and detachably couples shaft (6) via clutch (46), which couples the sun gear of gear set (P3) and the hollow gear of gear set (P1). Shaft (3) couples the ring gear of gear set (P2) and the carrier of gear set (P1), the sun gear of gear set (P1) couples the housing, the output shaft couples the ring gear of gear set (P3). Either, shaft (3) or shaft (6) is detachably coupled to the housing.
