19 Row Plate & Fin Trans Cooler

The DERALE 19 Row Plate & Fin Transmission Cooler (Model 13503) is a heavy-duty aluminum fluid cooler engineered to regulate automatic transmission temperatures under sustained driving loads. Featuring a plate-and-fin core design with 19 rows of cooling surface, this cooler delivers efficient heat dissipation in compact dimensions, making it ideal for performance builds, towing applications, and vehicles operating in high-temperature environments where stock cooling capacity falls short.

Constructed from aluminum and finished in durable black powder coat, the cooler measures 11.85 x 2.3 x 13.6 inches and weighs 2.68 lbs, fitting within tight engine bay configurations. The 3/8-inch hose barb inlet and outlet connections accept standard transmission cooler line sizes, simplifying integration into existing or custom hydraulic layouts. The 19-row fin stack maximizes surface area for heat transfer while the plate construction maintains structural integrity under pressure cycling. This core design is proven effective across transmission types and driving conditions, from highway cruising to extreme duty cycles.

This cooler addresses a critical need in modified and high-performance vehicles: transmission fluid that runs too hot degrades quickly, loses viscosity, and accelerates wear on clutches and seals. Builders working on street rods, turbocharged platforms, vehicles with engine swaps, towing setups, and off-road rigs rely on auxiliary cooling to extend fluid life and maintain consistent shift quality. The DERALE 13503 provides the cooling capacity required without requiring custom fabrication, making it a direct-bolt solution for transmission temperature management.
