Keep your transmission running cool and reliable with the BD Transmission Cooler Bypass Delete Kit for 2017–2019 GM 6.6L Duramax L5P trucks.
This kit eliminates the factory bypass valve, ensuring 100% of your transmission fluid flows through the cooler at all times, keeping temperatures as low as possible even under heavy loads. Unlike simple plugs, this kit includes a full replacement block designed to bypass the stock valve entirely. This prevents the common issue of debris causing the bypass valve to jam in recirculation mode, a problem that leads to rising transmission temperatures, potential overheating, and premature failure. With new seals included for an easy and secure installation, Drive confidently, knowing your transmission is cool and protected.
The BD Transmission Cooler Bypass Delete is an essential upgrade for anyone looking to extend the life of their transmission while enhancing its performance.
