Universal 12" Finned Aluminum Transmission Cooler – Dual Line, Double-Pass Design
Engineered for superior cooling performance, this Universal 12" transmission cooler features a high-grade finned aluminum construction that promotes rapid heat dissipation under high-load conditions. The cooler utilizes a dual line (double-pass) tube design, allowing transmission fluid to circulate through the cooler twice before exiting. This extended path significantly increases exposure to the cooling surface, dramatically reducing transmission fluid temperatures and enhancing overall transmission life and efficiency.
The 3-inch diameter body provides a balanced footprint—compact enough for tight spaces, yet robust enough for demanding applications such as towing, off-road, or high-performance street use. Precision-machined 1/4" NPT fittings offer versatile installation options, making it compatible with a wide range of vehicles and transmission setups. This cooler is ideal for users looking to upgrade from traditional radiator-integrated systems to a more efficient, standalone thermal management solution.
