Our fuel-efficient Maximizer™ High Torque Towing Converter is designed to reduce the slippage found in all non lock-up torque converters. This series of torque converters enables transmissions to run cooler and reduces engine RPM at highway speeds. In addition to the resulting fuel mileage increases, the High Torque 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.
