Quick Ship SKU #: PPE-125065000 PPE Transmission Oil Thermal Bypass Valve 17-19 GM 6.6L Duramax L5P

Eliminate the factory restrictive and problem prone OEM valve and add another layer of protection to your transmission in your L5P Duramax. 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 mechanical 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 part does not have this feature.
