Dual Pass Transmission Cooler Aluminum

The Dual Pass Transmission Cooler Aluminum is engineered for serious enthusiasts and mechanics who demand reliable transmission temperature management during high-performance driving, towing, or track use. Transmission fluid degradation accelerates dramatically above 200°F, compromising shift quality, torque converter efficiency, and component longevity—making an auxiliary cooler essential for modified vehicles, heavy-duty applications, or sustained hard driving.

This aluminum cooler addresses that critical need with a proven dual-pass design that maximizes heat rejection without excessive parasitic drag on your cooling system. Dual-pass construction forces transmission fluid through the cooler's core twice, effectively doubling dwell time and heat-transfer surface contact compared to single-pass designs. The aluminum core resists corrosion and handles both street and competition environments, while the compact 3.6 x 3.3 x 15-inch footprint allows flexible mounting in engine bays or auxiliary locations without consuming excessive space.

Weighing just 2.15 pounds, this cooler integrates easily into existing cooling lines, and the efficient pass design minimizes flow restriction—critical for maintaining adequate line pressure and shift timing across all gears. Installation is straightforward for any technician familiar with transmission plumbing; simply splice the cooler into the return or feed lines using appropriate adapters and secure clamps. This cooler is compatible with both manual and automatic transmissions, making it a versatile choice for various vehicles.
