Abstract
A continuously variable transmission includes four shift elements to establish three forward driving ranges and one reverse driving range. Two of the forward driving ranges utilize recirculating power flow paths in which the power transmitted through the variator is much smaller than the power transmitted by the transmission. Both variator sheaves rotate about axes that are offset from the input axis such that neither sheave is partially submerged in transmission fluid.
