Dual Pass Transmission Cooler Aluminum

The Racing Power Co-Packaged Dual Pass Transmission Cooler Aluminum (model R5050X) is a high-efficiency fluid cooling solution engineered for automatic transmissions in performance and heavy-duty applications. This dual-pass aluminum heat exchanger features a compact 12 x 3-inch core design that delivers superior thermal performance in confined engine bay spaces where cooling capacity cannot be compromised. The clear anodized aluminum construction provides corrosion resistance while maintaining excellent heat dissipation properties essential for extended transmission life under demanding conditions.

Key specifications include 1/2-inch NPT female inlet and outlet connections paired with 3/8-inch hose barb adapters, offering flexible plumbing integration into existing transmission cooling systems. The dual-pass design allows fluid to flow through both sides of the core simultaneously, maximizing residence time in the cooler and enabling greater heat rejection per gallon of coolant flow. At 2.15 lbs, this aluminum cooler delivers serious cooling performance without excessive weight penalty—critical for vehicles where every pound affects fuel economy and handling dynamics.

This transmission cooler suits enthusiasts upgrading street cars, drag racers managing sustained heat cycles, and truck owners towing heavy loads. Racing Power's engineering focuses on vehicles where stock cooling proves insufficient—whether under repeated hard acceleration, continuous highway towing, or extended transmission duty cycles. The NPT and hose barb adapter combination ensures compatibility across platforms while maintaining sealed, leak-free connections when properly installed with appropriate fittings and thread sealant.

Transmission cooler selection depends on heat load, flow requirements, and mounting location. The 12 x 3-inch footprint positions this cooler as a compact yet capable option for builds where space is limited but cooling demands are real. Dual-pass architecture distinguishes this from single-pass designs by improving thermal efficiency—fluid spends more time transferring heat to the aluminum core, resulting in lower transmission fluid temperatures across the entire operating range.
