What to consider before buying

When choosing a transmission cooler, consider your vehicle's typical load and driving conditions. For towing or racing, a stacked plate cooler with a fan (like the Derale) is recommended. For daily driving, a tube-and-fin cooler (Hayden) offers good value. Ensure compatibility with your transmission type and cooling system capacity. Proper installation with correct hose routing and mounting is crucial for performance.
