Claim:
1. A transmission comprising: a housing, an input shaft configured to receive torque from a drive unit, an output shaft configured to transmit torque to a load, a first gearset arranged between the input shaft and the output shaft, the first gearset being configured to receive torque from the input shaft, a second gearset coupled to the first gearset between the input shaft and the output shaft, a variable-ratio unit configured to transmit power between (i) a first member coupled to the input shaft and a first element of the first gearset and (ii) a second member coupled to a second element of the first gearset, a first torque transmitting mechanism arranged between the second gearset and the housing, the first torque transmitting mechanism being moveable between (i) a disengaged position in which the second gearset is decoupled from the housing and (ii) an engaged position in which the second gearset is coupled to the housing such that torque is transmitted through the second gearset, and a bypass torque transmitting mechanism arranged between the first member and the second member, the bypass torque transmitting mechanism being moveable between (i) a disengaged position in which the first member is decoupled from the second member and (ii) an engaged position in which the first member is coupled to the second member such that the variable-ratio unit is bypassed and torque is transmitted between the first member and the second member through the bypass torque transmitting mechanism.
