ABSTRACT:
A transmission with forward and reverse gears includes a drive and an output shaft, planetary sets, shafts and shift elements. The drive shaft communicates with a sun gear of the second planetary set and a shaft which communicates with the carrier of the first planetary set, and to the housing and is connectable with another shaft, which communicates with the carrier of the second planetary set and communicates with a shaft. This shaft communicates with sun gear of the first planetary set and the ring gear of the third planetary set. A shaft communicates with the ring gear of the second planetary set and the carrier of the third planetary set and can couple to the housing. A shaft communicates with the sun gear of the third planetary set and to the housing. The output shaft communicates with the ring gear of the first planetary set.
