Trans Cool Max Cool 9-7/8x11x3/4

The Trans Cool Max Cool 9-7/8x11x3/4 is a compact plate-and-fin transmission fluid cooler engineered for vehicles running automatic transmissions that demand reliable thermal management. As a seasoned mechanic, you know that automatic transmission fluid degrades rapidly under high heat—and that degradation accelerates wear on planetary gearsets, clutch packs, and seals. This aluminum cooler intercepts hot fluid returning from the torque converter before it cycles back through the transmission, dissipating excess heat and extending fluid life and component longevity. It's an essential upgrade for towing, high-performance driving, or any build where stock cooling proves inadequate.

Built from aluminum with black paint finish, the Trans Cool Max features a plate-and-fin core design that maximizes surface area for efficient heat transfer while maintaining a compact footprint. The cooler accepts 11/32-inch hose barbs at both inlet and outlet, allowing straightforward integration into existing transmission cooler lines or dedicated plumbing. Its slim profile—just 3/4 inch thick—fits in tight engine bays without extensive fabrication. The included fitting, hardware, and hose connections simplify installation, and the aluminum construction resists corrosion while offering excellent thermal conductivity for sustained cooling performance even under sustained load.

This cooler serves transmission builders, drag racers, truck owners hauling heavy loads, and any enthusiast upgrading a stock automatic transmission system. Installation typically requires basic plumbing work—tap into the transmission cooler return line, route fluid through the cooler core, and return it to the transmission. The universal 11/32-inch barb connection works with most aftermarket and OEM transmission cooler hose sizes, making it compatible across domestic and import platforms. Whether you're rebuilding a Turbo 400, a modern 10-speed, or anything between, the Trans Cool Max Cool 9-7/8x11x3/4 delivers measurable temperature reduction that protects your investment and improves reliability.
