OE cooler bypass valves allow transmission fluid to bypass the cooler and flow right back into the transmission, quickly raising the transmission temperature. These OE cooler bypass valves tend to fail, causing the transmission and torque converter to overheat and cause major damage. Our Full Flow Cooler Link connects transmission oil directly to the cooler, keeping the transmission temperature approximately 30° colder and eliminates the risk of the transmission and torque converter overheating. Unlike the OE bypass, our Full Flow Cooler Link won’t plug up and does not need to be removed to flush the cooler.
