Abstract:
1. A transmission comprising: an input member; an output member; a first shaft at least partially defining a first power flow path between said input member and said output member; a second shaft at least partially defining a second power flow path between said input member and said output member; first and second coaxial shafts further defining said first and second power flow paths, respectively; wherein said first and second shafts are countershafts spaced generally parallel with said input member, said output member, and said first and second coaxial shafts; a first torque-transmitting mechanism selectively engagable to at least partially establish power flow from said input member to said output member along said first power flow path; a second torque-transmitting mechanism selectively engagable to at least partially establish power flow from said input member to said output member along said second power flow path; a first torque sensor operatively connected to said first shaft for sensing an amount of torque carried by said first shaft; and a second torque sensor operatively connected to said second shaft for sensing an amount of torque carried by said second shaft; wherein said transmission is characterized by multiple speed ratios; wherein at least one of said speed ratios is characterized by power flow along said first path; and wherein at least another of said speed ratios is characterized by power flow along said second path.
