ABSTRACT:
The transmission has an input and output shaft, planetary gearsets, rotatable shafts, and shifting elements. A carrier of the gearset (RS4) and the input shaft are coupled to form the shaft (1). A ring gear of the gearset (RS2), a carrier of the gearset (RS3), and the output shaft are coupled to form a shaft (2). A sun gear of the gearset (RS1) and a sun gear of the gearset (RS4) are coupled to form shaft (3). A ring gear of the gearset (RS1) forms the shaft (4). A sun gear of the gearset (RS3) and a carrier of the gearset (RS2) are coupled to form the shaft (5). A carrier of the gearset (RS1) and a ring gear of the gearset (RS3) are coupled to form the shaft (6). A ring gear of the gearset (RS4) forms the shaft (7). A sun gear of the gearset (RS2) forms the shaft (8).
