A continuously variable transmission for varying the speed ratio of an outpu t shaft (47) relative to an input shaft (26) driven by a vehicle engine or other input power source. The power transmission includes a driven input member (21) coupled in driving engagement with at least one rotor (7) to transfer torque to the rotor. A disk member ( 1) is positioned in cooperative relationship with a rotatable shaft (2) and in driving engagement with the rotor (7), such that the disk member is driven to transfer torque to the rotatable shaft. An output member (49) is driven by the rotatable shaft, and torque is transferred from the shaft to the output member, with the disk member being selectively axially moveable relative to the rotor and to the rotatable shaf t in response to output load torque on the output member so as to vary the torque transferred from the rotor. A gear system (27) driven by the at least one rotor includes a planetary gear set (29, 30, 31) to extend the speed range of the output member.
