Abstract:
A transmission has an input member, an output member, at least four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The coupling members continuously interconnect a member of the first, second, third and fourth planetary gear sets with another member of the first, second, third and fourth planetary gear sets. The torque transmitting devices include clutches and brakes selectively engageable to interconnect at least one of the first, second and third members with at least one other of the first, second, third members and a stationary member and are actuatable in combinations of three to establish a plurality of forward gear ratios and one reverse gear ratio.
