Abstract:
A motor vehicle transmission having a housing, input and output shafts, shifting elements, a first planetary gearset having sun, ring and planet gears and a carrier and a second planetary gearset having planet gears and carriers that are rigidly coupled. The carriers of the first and the second gearsets are fixed, respectively, to the output and input shafts. A sun gear of the second gearset can be connected by a first shifting element to the housing and by a second shifting element to the input shaft. The ring gear of the first gearset can be connected by a third shifting element to the housing and by a fourth shifting element to the carrier of the first planetary gearset. The sun gear of the first gearset and ring gear of the second gearset are rigidly coupled, and the shifting elements are arranged in the housing and are accessible from the outside.
