22k Transmission Cooler

The 22k transmission cooler from DERALE is an essential upgrade for any vehicle experiencing elevated transmission fluid temperatures during towing, spirited driving, or extended highway use. Transmission fluid degrades rapidly above optimal operating temperature, leading to seal failure, shift quality degradation, and catastrophic transmission damage. This cooler addresses that vulnerability by supplementing your factory cooling system, maintaining fluid viscosity and protecting against thermal stress that factory cooling alone cannot manage.

DERALE engineered this 22,000 BTU-capacity unit with a stacked-plate aluminum core design that maximizes heat rejection efficiency while minimizing pressure drop across the circuit. The compact 13 x 2.3 x 18.8-inch footprint allows mounting in tight engine bay spaces without major fabrication, while the lightweight 4.5-pound construction prevents unnecessary load on engine bay brackets. Aluminum construction resists corrosion and integrates seamlessly with both synthetic and conventional transmission fluids, delivering reliable performance across diverse climates and operating conditions.

This transmission cooler serves mechanics and enthusiasts upgrading vehicles for towing capacity increases, track duty, or severe-service longevity. Installation requires basic hose routing from the transmission pan or factory cooler ports—no deep engine disassembly necessary on most applications. Whether you're protecting a stock rebuild or fortifying a high-horsepower build, the 22k transmission cooler provides the thermal margin needed to keep transmission fluid in the 180–200°F sweet spot where fluid life and shift quality remain optimal.
