A transmission includes a housing, an input member connectable to an engine output member, a sleeve member, and a launch clutch assembly connected to the input member and to the sleeve member, wherein the launch clutch is selectively engageable to transmit torque from the input member to the sleeve member. A first countershaft is rotatably supported within the transmission housing. A second countershaft is rotatably supported within the transmission housing. A plurality of co-planar gear sets are connected to the input member, sleeve member, and the countershafts. A plurality of torque transmitting mechanisms are provided for coupling various components of the co-planar gear sets to the input member, sleeve member, and countershafts. The selective engagement of the launch clutch assembly and the torque transmitting mechanisms establishes at least one of five forward speed ratios and a reverse speed ratio.
