2019-2023 Ram 1500 3.0L EcoDiesel Transmission Pans

The stock thermostatic valve in your Ram EcoDiesel's transmission cooling system has a bad habit of getting stuck closed, which prevents transmission fluid from getting from your truck's transmission to its transmission cooler. Needless to say, this is a BAD thing that can lead to high transmission temperatures, limp mode, or even transmission damage. Tier One's selection of 2019-2023 Ram 3.0L EcoDiesel Thermal Bypass Valves delete the stock valve, allowing full-time fluid flow from your truck's transmission to its transmission cooler, giving your tough EcoDiesel Ram improved reliability and lower running temperatures.
