Specifications sourced from the Davies Craig Transmission & Engine Oil Cooler range.
Heat is the leading cause of automatic transmission wear and premature failure. Towing, off-road driving, steep climbs, heavy loads and prolonged highway driving all increase transmission fluid temperatures, causing fluid breakdown and excessive wear on internal components.
The Davies Craig Ultra-Cool® Transmission Oil Cooler removes excess heat before the fluid returns to the transmission, helping maintain optimum operating temperatures, improve shift quality and significantly extend transmission service life. For vehicles with high steering loads, the #404 also provides outstanding cooling performance as a super heavy-duty power steering oil cooler.
