18In Dual Pass Trans mission Cooler

The 18In Dual Pass Transmission Cooler from Racing Power Co-Packaged is engineered to manage transmission fluid temperatures in high-performance and modified vehicles where factory cooling capacity falls short. This cooler is essential for street machines, tow vehicles, and track-oriented builds that demand consistent thermal management to extend transmission life and maintain shift quality under sustained load. Whether you're upgrading a naturally aspirated engine build or managing heat in a turbocharged application, this transmission cooler addresses the cooling deficit that occurs during aggressive driving, heavy towing, or extended highway cruising.

The dual-pass core design maximizes heat transfer efficiency by directing fluid through the cooler in two separate paths, allowing greater contact time with the cooling fins and delivering superior temperature reduction compared to single-pass units of the same physical footprint. At 3.6 inches wide by 3.4 inches tall and 20.6 inches in length, this compact yet effective cooler fits in tight engine bays and behind-grille mounting locations common to most street and race applications. The aluminum construction provides excellent thermal conductivity while maintaining lightweight durability, and the 18-inch length accommodates vehicles with standard radiator support widths without modification to core components.

This transmission cooler is ideal for builders and enthusiasts running automatic transmissions that see elevated fluid temperatures—particularly those with performance torque converters, stall upgrades, or aggressive gear ratios that increase parasitic heat. Installation requires integration into the transmission cooler line circuit, typically using -6AN or -8AN hose depending on your vehicle's original setup. The compact 3.05-pound weight makes this an easy bolt-on upgrade for nearly any transmission-equipped platform, and the Racing Power Co-Packaged engineering ensures compatibility with common manifold and radiator hose routing configurations across domestic muscle cars, trucks, and performance imports.
