Keep the 68RFE Fluid Cool

January 2020 Products DT Staff

Debris in the stock cooler bypass valve can cause it to jam up the internal valve, thus keeping the transmission fluid from going all the way through the transmission cooler and holding it in recirculation mode. That can lead to the transmission overheating and possibly failing prematurely. As a replacement to the RAM 68RFE factory bypass valve, BD Diesel Performance's Cooler Bypass Delete keeps your cooler fully operational at all times and eliminates an item prone to failures in the transmission, thus keeping your transmission temperature as low as possible.
