The fuel-efficient TCI Maximizer Towing Converter is designed to reduce the slippage found in all non lock-up torque converters. The Maximizer series enables transmissions to run cooler and reduces engine RPM at highway speeds. In addition to the resulting fuel mileage increases, the Maximizer Towing Converter also lowers transmission temperature by as much as 20° F. This is an excellent choice for motor homes, tow vehicles and other heavy load applications. Stall speeds range from 1,000 to 1,200 RPM.
