This is a direct-fit Translife Transmission Oil Cooler Kit for the 87-01 Jeep Cherokee (XJ) with Flex-a-fit radiator. The Translife cooler provides additional cooling to protect your transmission, using Turbulators inside the tubes for superior heat transfer. Tests have proven that a 20 degree drop in transmission fluid temperature can double the life of automatic transmission components. Cooler transmission oil gives more reliable, consistent shifts under racing conditions and prevents transmission damage. Kit includes direct-fit bracket, cooler, rubber hose, GatorClips and hose clamps.
