ABSTRACT:
An automatic transmission for engine driven vehicles, in which there is a torque converter and a planetary gear system, and linkage means whereby the leverage between the fluid torque converter and the planetary system is controlled by a vacuum generated by the varying torque of the engine under various load conditions. It includes a primary impeller and turbine, and a secondary impeller and turbine, the latter turbine being movable in variable spacing from the secondary impeller, to vary the torque therebetween, the secondary turbine being coupled to an annular ring gear which also intermeshes with planetary pinions rotatable about a sun gear, which movement is controlled by the engine manifold vacuum and accelerator.
