Abstract
An automatic transmission is disclosed including a continuously variable transmission assembly having a first pulley and a second pulley. At least one of the pulleys has a variable operating diameter to provide a variable ratio. A first gear assembly and a second gear assembly are provided each including at least one forward gear. The forward gears have different diameters and are numbered consecutively in the order of increasing diameter. The continuously variable transmission assembly also has at least one pulley actuator that selectively adjusts the variable diameter of the at least one of the pulleys to change the variable ratio of the continuously variable transmission assembly in response to a shift between the at least one forward gear of the first gear assembly and the at least one forward gear of the second gear assembly.
