The Derale Performance Transmission Cooler Kit is a practical upgrade for drivers who want to protect their transmission and maintain reliable performance under heat and load. Designed for medium sized cars, compact trucks and SUVs with light duty towing duties, this tube and fin cooler helps reduce fluid temperatures that can lead to poor shifting and premature transmission wear. By improving cooling efficiency, it supports smoother operation and helps extend transmission life in demanding driving conditions.

Built with 1/2 inch copper tubing expanded into aluminum cooling fins, this 6 pass cooler is engineered to move heat away from transmission fluid efficiently. The compact design makes it suitable for a wide range of applications, while the included hardware kit simplifies installation on vehicles with 5/16 inch transmission cooler lines.
