5 Row Plate & Fin Cooler (1/2in FPT)

The DERALE 5 Row Plate & Fin Cooler (1/2in FPT) is a high-capacity fluid cooler engineered for automatic transmission temperature management in performance and modified vehicles. This aluminum plate-fin design delivers efficient heat dissipation in applications where factory cooling falls short—particularly in heavy-duty driving, towing, and high-performance builds where transmission fluid temperatures can climb dangerously above optimal operating range.

The five-row core configuration maximizes surface area for heat exchange while maintaining a compact profile. The 1/2-inch female pipe thread (FPT) ports accommodate standard transmission cooler line adapters, making integration straightforward into existing cooling circuits. Black anodized aluminum construction provides corrosion resistance and durability in both street and off-road environments. At 1.5 lbs, the cooler integrates easily into engine bays with spatial constraints, while its 11.9 x 2.35 x 13.6-inch dimensions allow flexible mounting behind bumpers, grilles, or intercooler stacks without requiring extensive modification.

This cooler is ideal for owners of lifted trucks, modified muscle cars, and vehicles subject to sustained high load conditions—situations where transmission temperature spikes reduce fluid viscosity and accelerate clutch pack wear. Upgrading to a multi-row cooler extends transmission lifespan by maintaining consistent fluid temperature across varying driving conditions. DERALE's plate-fin design is proven in motorsports and heavy-duty applications, offering superior cooling efficiency compared to single-row designs.

When selecting an automatic transmission cooler, prioritize core row count and material durability. The five-row configuration strikes the balance between cooling capacity and pressure drop, ensuring your transmission operates within safe thermal parameters without starving the system of flow during cold starts.
