Add another measure of protection and increase fluid flow to transmission cooler increasing cooling capacity with the easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve for the Ram Cummins diesel.

The OEM part has restrictive internal passages. When the OEM valve fails in the open position, transmission fluid doesn’t reach your cooler. This can be caused by mechanical failure or debris. The result of stock valve failure can cause the transmission to dangerously overheat. Without properly cooled transmission fluid, the demands of towing and rigorous stop-and-go driving conditions shorten the life of transmission components.

The PPE Bypass eliminates the extremely restrictive mechanical factory valve which maximizes fluid flow from the transmission cooler. For further protection, a Neodymium magnet equipped service plug has been added. The removable plug traps ferrous debris and can be accessed to remove particles from the system. The factory bypass valve does not have this feature.
