Abstract
A multi-speed transmission may include an input member and an output member disposed in a housing. A first planetary gear set, a second planetary gear set, a third planetary gear set, and a fourth planetary gear set may be disposed within the housing, each planetary gear set including a sun gear, a planet carrier, and a ring gear. Six control elements may be operably coupled to each of the planetary gear sets and selectively engagable to create a set of different gear ratios between the input member and the output member. The set of different gear ratios may include at least ten forward gear ratios and at least one reverse gear ratio.
