Abstract of the Disclosure A method for shifting a transmission with predominatly mechanical speed sensing actuator to within a 10 percent shifting zone around a chosen operating line on an engine rpm/torque map by matching the force balance of the driver pulley to a force balance of the driven pulley. A variable speed belt drive transmission system with a predominantly mechanical speed sensing driver pulley and a torque sensing driven pulley that responds to an operating line, monotonic in torque having a slope from about .004 lb ft/ rpm to about .060 lb-ft/ rpm where the driver pulley has an actuator that controls speed for a chosen torque value. The actuator has at least one centrifugal weight connected to an end of a torque producing spring to wind the spring. A second end of the spring is operatively connected through an articulated linkage to a movable half of the pulley such that the generated axial force is not directly proportional to square of the speed.
