Trans Cooler 15x5 12000 GVW

The Trans Cooler 15x5 12000 GVW by ALLSTAR PERFORMANCE is a compact yet effective transmission cooling solution engineered for vehicles operating at their weight limits. This aluminum core cooler addresses a critical performance need: automatic transmissions generate excessive heat under sustained load, towing, or high-performance driving, which degrades fluid viscosity, reduces shift quality, and accelerates internal wear. Whether you're a weekend racer, weekend warrior towing capacity, or someone pushing a heavily modified vehicle, maintaining optimal transmission temperature directly impacts longevity and drivability.

This unit's 15x5-inch core footprint delivers efficient heat rejection without consuming excessive underbody real estate, a design priority for street-driven and competition vehicles alike. The 12000 GVW rating indicates this cooler is engineered for medium to heavy-duty applications where thermal load is significant and margin for error is minimal. Aluminum construction resists corrosion while providing superior thermal conductivity compared to plastic components, ensuring consistent cooling performance across seasons and duty cycles. The compact dimensions (10.8 x 1.9 x 16.5 inches) and lightweight design (2.07 lbs) allow straightforward installation in confined engine bays or auxiliary cooling loops without compromising weight distribution or clearance.

Mechanics and fabricators typically spec this cooler for street rods, custom trucks, and performance-built automatics where factory cooling proves marginal. It integrates seamlessly into existing cooling circuits via standard hose fittings and operates passively (relying on airflow) or can be paired with auxiliary electric fans for enhanced capacity. Installation requires basic plumbing knowledge and appropriate hose routing to avoid kinks or restriction; professional setup ensures longevity and prevents leaks. This cooler suits any build targeting reliable, repeatable transmission performance without the complexity of larger, heavier industrial-grade units.
