The factory liquid-to-liquid transmission oil cooler on the 2003-2007 Dodge Ram 5.9L Cummins uses engine coolant to regulate transmission fluid temperature. When the unit wears out it can leak coolant into the transmission fluid, a mix that can destroy a transmission. This Mishimoto replacement is a direct-fit, OEM-equivalent oil cooler that installs with no modification, letting you replace the factory cooler preventatively before it fails. Made to OEM specifications in corrosion-resistant aluminum, it includes a new powder-coated bracket and brass fittings.
