A transmission that functions as a combination friction drive and gear tooth drive: The transmission utilizes VCT conic teeth added to the surface of a variable pulley. The teeth in the sides of a continuous loop, or a two-faced gear, engage the teeth on this conic surface. When the pulleys contract or expand, the top of the teeth engage the surface frictionally. When the contraction or expansion of the pulleys move the continuous loop, or two-faced gear, to the next ring of conic teeth, it engages the conic teeth as a toothed drive.
