Dieselr Transmission Cooler Thermal Bypass Valve Cummins 6.7L (2019-2022)

Transmission Cooler Thermal Bypass Valve for 6.7L Cummins

The Dieselr Transmission Cooler Thermal Bypass Valve Cummins 6.7L (2019-2022) replaces the restrictive factory bypass assembly to allow consistent transmission fluid circulation through the cooler circuit. Engineered specifically for late-model 6.7L Ram Cummins platforms, this component supports predictable temperature control under load.

By eliminating delayed cooler engagement behavior found in the OE configuration, this upgrade promotes more stable transmission operating temperatures during towing, daily driving, and extended highway use.
