Abstract
A transmission includes an input member, an output member, four planetary gear sets, and a plurality of torque transmitting mechanisms that are selectively engageable to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member. The transmission further includes one or more locking mechanisms that engage one or more of the plurality of torque transmitting mechanisms during a start/stop event.
