Abstract
A transmission with forward and reverse gears comprising planetary gearsets, shafts and shift elements. The sun gear of gearset (P) couples shaft () that is connectable, via brake (), to housing (G). The carriers of gearsets (P, P) couple shaft () which is connectable, via clutch (), to drive input shaft (). Input shaft () is connectable, via clutches (), respectively to shafts (). Shaft () couples the ring gear of gearset (P). Shaft () is connectable, via brake (), to housing (G) and couples the sun gears of gearsets (PP). The ring gears of gearsets (PP) couple drive output shaft (). The carrier of gearset (P) couples shaft () which couples a component connecting the ring gear of gearset (P) and the sun gear of gearset (P). The carrier of gearset (P) couples shaft () which is connectable, via brake (), to housing (G).
