Upgrade Your Transmission Cooling System!

“A friend recommended this upgrade to me, but I was hesitant. Me mess with my transmission? I don't think so. But, after I watched several videos, I took the plunge. The item is well manufactured. High-quality parts. Instructions were clear as well.” - DAE


Why Get Our Cooler Flow Bypass Valve Kit?


✅Reduces Heat: Without proper cooling, your transmission fluid can overheat, especially when towing, off-roading, or driving on highways for long periods. The Cooler Flow Bypass Valve Kit is an upgrade designed to improve cooling in GM automatic transmissions like the 6L80, 6L90, and 8L90. It prevents overheating, a major cause of transmission failure, ensuring consistent cooling and reducing the risk of serious damage.

✅Prevents Damage: It reduces average operating temperatures by as much as 20%, helping to keep the transmission fluid within an ideal range for better performance. This also reduces the risk of overheating under heavy load, such as towing or off-roading, while increasing the life of the automatic transmission fluid (ATF), which helps maintain smoother shifting and overall transmission health over time.


✅Convenient Design: Features a built-in safety bypass that ensures the transmission fluid is always at the correct level, even during extreme conditions. This design allows for immediate cooler fill, meaning the transmission fluid is efficiently circulated and cooled immediately, reducing the overheating risk. Additionally, the kit provides the ability to perform an accurate fluid level check without the need for a warm-up cycle, saving time and ensuring your transmission is always in optimal condition.
