Mishimoto Transmission Cooler for Dodge Ram 6.7L Cummins 2013-2018

Mishimoto Transmission Cooler for Dodge Ram 6.7L Cummins (2013–2018) Protect your transmission — the 6.7L Cummins in Dodge Ram trucks can transmit up to 930 lb-ft of torque, producing significant heat. Excessive transmission temperatures shorten component life and lead to costly failures. The Mishimoto Transmission Cooler system keeps fluid temperatures in check for reliable performance under load. Key Features Direct-fit design for 2013–2018 Dodge Ram 6.7L Cummins (68‑RFE and Aisin AS69RC). Improved thermal bypass valve — CNC-machined aluminum body with replaceable thermostat that opens ~10°F earlier than stock for quicker cooling engagement. Selectable full-flow bypass for hot‑climate or heavy‑towing use; tool-swappable with a single wrench. Enhanced flow and cooling in both bypass configurations; cooling fins machined into the valve body increase heat dissipation. Durable finish & lifetime guarantee — black anodized finish and backed by the Mishimoto Lifetime Guarantee. Benefits By replacing the failure-prone factory thermostat and bypass, this kit ensures consistent fluid flow to the cooler, prevents overheating, and extends transmission life. Ideal for towing, heavy duty use, or trucks operating in hot climates. Upgrade with confidence — precision engineering, better cooling performance, and long-term durability make the Mishimoto Transmission Cooler an essential upgrade for Dodge Ram 6.7L Cummins owners.
