STL010 6L80/90 2014 & Up Sure-Cool System

The STL010 Sure-Cool System is an innovative solution designed to ensure full-time cooler flow in 6L80/90 transmissions from 2014 and newer. By addressing common cooling issues, this system helps maintain optimal transmission temp, ensuring your vehicle operates efficiently under demanding conditions. Whether you’re towing heavy loads, driving in extreme climates, or upgrading for performance, the Sure-Cool System is a game-changer for preserving transmission health and longevity.

Traditional cooling systems can restrict flow, especially when operating under lower pressures, leading to elevated transmission temp and potential wear on critical components. The STL010 leverages advanced cooler bypass technologies to provide consistent cooling. By bypassing factory restrictions, it allows continuous flow through the transmission cooler, reducing temperature spikes and promoting uniform heat dissipation.

The benefits of the STL010 Sure-Cool System include improved cooling efficiency, significantly lower transmission temp, and enhanced durability for your transmission. Maintaining a lower and more stable operating temperature can prevent overheating, extend the life of your transmission fluid, and reduce wear on internal components.

Choose the STL010 Sure-Cool System for unmatched cooling performance backed by proven cooler bypass technologies. With full-time cooler flow, your transmission is better equipped to handle the toughest driving conditions, ensuring peak performance and long-term reliability. Upgrade to the STL010 today and experience the difference it makes for your 6L80/90 transmission.
