Frame Rail TransCooler2 Pass -6AN

The Frame Rail TransCooler2 Pass -6AN from PERMA-COOL is a reliable transmission cooling solution designed for automotive enthusiasts and mechanics who require effective thermal management in tight spaces. Its compact two-pass design is ideal for vehicles where larger radiator-style coolers cannot fit, making it suitable for street performance, towing, and track applications.

This cooler features a two-pass aluminum core that maximizes fluid dwell time and heat dissipation efficiency by routing transmission fluid through the cooler twice before returning to the transmission. The -6AN inlet and outlet ports are compatible with standard braided stainless steel transmission cooler lines, allowing for easy integration into existing or custom cooling circuits.

Engine builders, transmission specialists, and modification shops will find the TransCooler2 beneficial for high-performance builds on muscle cars, street rods, and drag vehicles where factory transmission cooling may not suffice. Its lightweight design, weighing just 1.25 lbs, helps maintain suspension geometry and minimizes unsprung mass, which is crucial for both street and race applications.
