ABSTRACT:
A powertrain includes a continuously variable transmission having a starting mechanism, a continuously variable unit (CVU), and a pair of planetary gear arrangements. The continuously variable transmission also includes a plurality of torque transmitting mechanisms which are selectively engageable in combinations of two to establish a reverse mode of operation between the starting mechanism and a transmission output shaft, a low direct mode of operation, an intermediate split mode of operation, and a high split mode of operation.
