Abstract: A transmission includes a transmission housing, six co-planar gear sets, a first and second input shafts, an output member, a first and second countershaft, and six synchronizer assemblies. The six synchronizer assemblies are selectively engaged to establish one of at least eight forward speed ratios and one reverse speed ratio between the transmission input shaft member and the output member.
