Abstract
An automatic transmission power train including an improved torque-pressure transducer incorporating dual concentric outer turbine and inner transducer shafts, secured together at their input ends, and having a regulating valve mounted in the center of their output ends, with the axial movement of the regulating valve being controlled by a plurality of spring-loaded, axially aligned cam members, each having oppositely disposed tabs formed thereon for alternately extending through one set or both sets of oppositely disposed relatively movable longitudinal slots formed in the two shafts, with the spread of the cam members being changed by camming action in response to the relative twists of the concentric shafts, and the regulated transducer pressure thus produced being directed to a modulator valve assembly for transmittal to the conventional transmission shift valves.
