PPE Transmission Cooler - Ram 2500 3500 6.7L Cummins 2015-2018 224064000

Excessive heat is the number one contributor to transmission failures, leading to issues like clutch pack slipping, clunky shifting, and fluid breakdown. The PPE all-aluminum transmission cooler features a massive 360 cubic-inch core, 118% larger than stock, with a 28% larger frontal area for increased airflow and enhanced heat dissipation. Its dense, louvered external fins maximize heat transfer to ambient air, achieving a temperature drop of up to 30°F. The heavy-duty bar and plate construction provides significantly greater cooling mass and flow capacity compared to factory tube and fin designs, offering superior pressure resistance and durability for performance applications.
