Product Description
The BD DIESEL 1061530 Cooler Bypass Delete is engineered to eliminate the failure-prone stock bypass valve on GM 6L80 automatic transmissions used in 2014–2018 Chevrolet and GMC trucks. When the factory bypass valve sticks in recirculation mode, transmission fluid bypasses the cooler, which can allow temperatures to climb and lead to overheating and premature transmission failure. This delete ensures cooler fluid always flows through the cooler for optimal temperature control.
The cooler bypass delete installs in place of the stock bypass valve and comes with all required seals and a magnetic service plug for maintenance. This simple upgrade can help reduce transmission operating temperatures, improve fluid life, and add reliability to trucks that see towing, heavy use, or high idle times.
