This bypass plug fits GM GMC, Chevrolet, Cadillac and other models equipped with 6L80, 6L90, 8L90 transmissions.
Crafted from high-grade aluminum alloy, our bypass plug features an upgraded dual-seal design for superior sealing. It delivers exceptional corrosion resistance and reliable long-term operational stability for your transmission system.
This transmission cooler thermostat bypass plug works with the cooler bypass valve to ensure full cooling system operation. It effectively lowers transmission operating temperature, greatly extending the service life of your transmission.
No professional tools required! This 100% plug-and-play plug fits directly into the bypass valve to boost transmission cooling. For faster, smoother setup, apply a small amount of transmission fluid to the O-ring before installation.
Please confirm your transmission model before purchase to ensure proper fit and optimal cooling performance. If the Cooler Melt Bypass Plug has any problems during use, please feel free to contact us, and we will provide you with a satisfactory solution.
