Enhance the reliability and cooling performance of your 2013–2018 Ram 6.7L Cummins with the Norcal Diesel Performance Transmission Cooler Thermal Bypass Valve Upgrade. This direct replacement is designed for Ram trucks equipped with 68RFE or Aisin AS69RC transmissions and addresses the common overheating issues caused by the factory bypass valve.
The original thermal bypass valve can restrict fluid flow and, if it fails, may prevent transmission fluid from reaching the cooler. This can result in high transmission temperatures, especially when towing or hauling heavy loads, putting your transmission at risk for overheating and expensive repairs. Our upgrade eliminates this restriction, ensuring that transmission fluid consistently flows through the cooler for optimal temperature control and protection.
Built from high-quality materials for a precise fit and lasting durability, this thermal bypass valve upgrade is easy to install and requires no permanent modifications. The kit includes all necessary seals and fittings, making it a straightforward bolt-on solution for both DIYers and professional installers. With improved fluid flow, you can expect lower transmission temperatures, longer fluid life, and better performance under demanding conditions.
Protect your Ram’s transmission and drive with confidence—choose the Norcal Diesel Performance Transmission Cooler Thermal Bypass Valve Upgrade for reliable cooling and peace of mind on every journey. This is a must-have upgrade for any Ram owner looking to maximize transmission longevity and performance.
