ABSTRACT:
A multi-speed automatic transmission includes a first planetary gear set and a second planetary gear set, which are arranged in parallel on a first output shaft and a second output shaft, respectively. An input shaft is connectable with a first ring gear through first input drive and driven gears of the input shaft and the first output shaft, being connectable with a second pinion carrier through a second input drive and driven gears of the input shaft and the second output shaft. The first output shaft is connectable with a first pinion carrier, the second output shaft being connectable with a second ring gear. A second pinion carrier is fixable to a transmission case. The first and second sun gears are connectable with the input shaft through the first input drive and driven gears and through the intermediate gear, being fixable to the transmission case.
