# BD Diesel 13-18 Dodge 6.7L 68RFE/Aisin AS69RC Thermostat Bypass

Debris in the stock cooler bypass valve can cause it to jam the internal valve keeping it in recirculation mode. When this happens the transmission temperature will rise and can lead to overheating and premature transmission failure. The BD Cooler Bypass Delete keeps the transmission cooler operational all the time and eliminates this failure prone item.

-   Ensures 100% Fluid Flow Through The Transmission Cooler
-   Keeps Your Transmission Temperature As Low As Possible
-   Fits 66RFE / 68RFE / AS66RD / AS69RC Transmission
-   Fits 68RFE And Aisin AS69RC Transmission
-   Eliminates Factory Bypass Valve
