ABSTRACT:
A transmission is provided having four planetary gearsets, each having respective first, second, and third members, and a plurality of selectively engageable torque transmitting devices configured to selectively interconnect selected members of the four planetary gearsets for unitary rotation thereby to provide a plurality of forward speed ratios and at least one reverse speed ratio between an input member and an output member.
