Abstract

A transmission which has drive input and output shafts, a housing, two planetary gearsets (PR, PR), and at least three shifting elements which produce three gears or ratios. A ring gear of the gearset (PR) and the input shaft are connected for forming a first shaft, a carrier of gearset (PR) and the output shaft are connected for forming a second shaft, a ring gear of gearset (PR) forms a third shaft, sun gears of gearsets (PR, PR) are connected for forming a fourth shaft, and carrier of gearset (PR) couples the housing. The first shifting element is arranged in the force flow between the third shaft and the housing, the third shifting element is arranged in the force flow between the second and third shafts, and the second shifting element is arranged in the force flow either between the first and second shafts or the second and fourth shafts.
