A liquid crystal display includes a liquid crystal panel including a number of thin film transistors, a timing control circuit, a common voltage generating circuit and a gamma circuit. The selectable torque transfer devices are engaged singly or in combinations of two to yield an EVT with a continuously variable range of speeds and four mechanically fixed forward speed ratios. A heater heats the air flowing through the passageway to a predetermined temperature, a flash evaporator being in communication with the passageway.
