The BD Diesel Cooler Bypass Delete addresses a potential issue in the factory transmission cooler bypass valve of 2019-2024 Dodge 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins engine and either the 68RFE or AS69RC transmission. Debris accumulation within the stock bypass valve can lead to the internal valve becoming stuck in the recirculation mode. This malfunction prevents proper cooling, potentially causing elevated transmission temperatures, overheating, and ultimately, premature transmission failure.
The BD Cooler Bypass Delete offers a straightforward solution by permanently bypassing this failure-prone factory component. This modification ensures that transmission fluid flows through the cooler at all times, contributing to lower operating temperatures and enhanced transmission longevity.
