Abstract:
1. A transmission comprising: an input member; first, second, third, fourth, and fifth co-planar gear sets each having a first gear member intermeshed with a second gear member, and wherein the third and fourth gear sets each include a third gear member intermeshed with the first gear member; a first intermediate member continuously interconnected with a first plurality of the first gear members; a second intermediate member concentric with the first intermediate member and continuously interconnected with a second plurality of the first gear members; a countershaft selectively connectable with a first plurality of the second and third gear members; an output member selectively connectable with a second plurality of the second and third gear members; a torque transmitting assembly selectively engageable to interconnect the input member with at least one of the first and second intermediate members; four synchronizer assemblies for selectively coupling the second and third gear members of the first, second, third, fourth, and fifth gear sets with one of the countershaft and the output member; a first transfer gear set interconnected between the countershaft and the output member for transferring torque from the countershaft to the output shaft, and wherein the torque transmitting assembly and four synchronizer assemblies are selectively engageable in combinations of at least two to establish at least seven forward speed ratios and at least one reverse speed ratio between the input member and the output member.
