Abstract
A multi-speed transmission includes a housing; an input member and an output member; four planetary gear trains including a first planetary gear train, a second planetary gear train, a third planetary gear train and a fourth planetary gear train, wherein each of the planetary gear trains includes a ring gear, a planetary carrier and a sun gear; and six control elements. Each of the six control elements is operatively connected to at least one of the planetary gear trains and selectively engageable to produce a set of different speeds between the input member and the output member. The set of different speeds includes eight forward speeds and two reverse speeds.
