Combat excessive fluid temperatures, prevent thermal breakdown, and safeguard your automatic transmission under heavy towing and high-output use with transmission cooling components engineered for the 2019–2026 5th Gen 6.7L Cummins. Heavy loads, steep grades, and aggressive power adders generate massive heat within your transmission system, which can rapidly degrade fluid and cause premature component wear. Upgrading to high-capacity transmission coolers, thermostats, and auxiliary cooling lines ensures optimal operating temperatures, enhances fluid life, and delivers maximum reliability for your heavy-duty Ram.
