Abstract
A transmission includes an input member, an output member, a plurality of torque-transmitting mechanisms that are selectively engageable to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member, and one or more latches associated with one or more of the torque-transmitting mechanisms. The one or more latches engages the respective torque-transmitting mechanisms during or prior to a start event.
