Why would I want to eliminate the factory bypass valve?

The factory bypass valve can get jammed by debris, keeping transmission fluid from flowing to the cooler. This kit removes that valve, ensuring constant flow to the cooler and helping to prevent transmission overheating and damage.

What is the magnetic service plug for?

The included magnetic service plug helps to capture any small metal particles that might be circulating in your transmission fluid. This can be a useful diagnostic tool and helps keep the fluid cleaner.

Does this kit come with everything needed for installation?

Yes, the kit includes all the new seals required for installation. You will need basic hand tools to complete the job, but no special tools are typically required.

Product Details

Debris can sometimes jam the factory bypass valve in your GM 6L80 transmission, locking it in recirculation mode. When this happens, the transmission fluid doesn't reach the cooler, causing temperatures to rise and potentially leading to overheating and premature failure. This Cooler Bypass Delete kit from BD Diesel eliminates that failure-prone factory valve entirely.

By removing the bypass valve, this kit ensures that 100 percent of your transmission fluid is always flowing through the external cooler. This helps keep your transmission temperatures as low as possible, which is especially important if you're towing, hauling heavy loads, or driving in demanding conditions. The kit includes all the necessary seals for installation, plus a magnetic service plug to help catch any stray metal particles in the fluid.

This bypass delete is a solid option for anyone looking to improve the reliability and cooling efficiency of their GM 6L80 transmission. It's a straightforward way to remove a known weak point in the factory system.
