Cooler Flow Bypass Valve Kit - Compatible with GM 6L80 6L90 8L90 10L90 Transmissions (2014+) - Replaces #STL010 Helps Combat Transmission Overheating

Cooler Flow Bypass Valve Kit

• 【Drop Transmission Temperatures by Up to 20°F】Stop heat from damaging your transmission. This upgrade kit replaces the restrictive factory thermostat, unlocking full cooler flow to lower average operating temperatures by up to 20°F. This engineering choice supports more aggressive heat dissipation, helping to maintain lower transmission temperatures under load.
• 【Direct Replacement Thermal Bypass Valve Kit】This kit provides a direct, bolt-on solution to replace the factory valve (Part #STL010). It is designed for use in 2014+ GM vehicles, including Chevrolet, GMC, and Cadillac models equipped with the 6L80, 6L90, 8L90, or 10L90 transmission. Installation requires no modifications.
• 【Instant Cooler Filling & Accurate Cold Fluid Checks】Features an integrated safety bypass that ensures the transmission cooler fills immediately. This design allows for accurate fluid level checks when the transmission is cold, eliminating guesswork and the risk of dangerous over-filling or under-filling.
• 【High-Quality Materials for Long-Term Reliability】Manufactured to strict quality standards using durable materials, this valve is built to withstand the high temperatures and vibrations under the hood. It's an investment in stable performance and long-term reliability for your transmission.
• 【Extend Transmission Life & Enhance Shifting Performance】This is proactive preventative maintenance. By maintaining consistently lower temperatures, this upgrade reduces wear on critical internal components like clutches and seals, leading to smoother shifting and a significantly extended transmission lifespan, potentially saving you from a costly future rebuild.
