ABSTRACT:
A multi-speed automatic transmission includes an input shaft, a first out put shaft having a first planetary gear set, and a second output shaft having a second planetary gear set. The shafts are in parallel with one another. The input shaft is engageable with the first ring gear and the second carrier. The first output shaft is engageable with the first carrier. The second output shaft is engageable with the second ring gear. The first and the second sun gears are engaged with an intermediate gear which can be held to a transmission case by a first brake arranged between the intermediate gear and the first and second planetary gear sets, and being connectable with the input shaft via the input drive gear and the first input driven gear. The second carrier can be held to the transmission case.
