LS Transmission Cooler Line Kit for 6L80E to 10L90E
When dropping a 6L80E or 10L90E transmission into an LS chassis, factory cooler hoses often end up wrapped around exhaust manifolds and tight frame openings that drive fluid temperatures upward and sap system pressure. This cooler line kit designed for GM 6L80E and 10L90E applications installs a billet aluminum manifold at the tail housing and pairs it with stainless steel braided hoses routed well clear of heat sources. By matching GM port locations with CNC machined fittings, it allows an installation without case modifications that seals under pressure and keeps fluid paths straight for even cooling during spirited shifts or sustained track use. Installation is straightforward thanks to precisely sized hoses, factory thread forms and protective covers that guard against abrasion and radiant heat damage in tight engine bays.
Precision Machined Billet Manifold for Smooth Fluid Flow
The billet aluminum manifold is crafted using multi axis CNC machining to align perfectly with GM transmission ports, eliminating any need to alter the case. This precision engineered design reduces turbulence by providing straight, uniform passages that guide fluid evenly through the cooler lines. By mirroring the shape of the 6L80E and 10L90E tail housing, the manifold ensures a seamless fit that resists leaks and maintains system pressure under load. Even distribution of transmission fluid helps prevent localized heat buildup, promoting consistent temperature control during repeated shift events. As a result, critical components such as clutch packs and bearings experience less thermal stress, extending service life under aggressive driving conditions.
Durable Stainless Steel Hose Assembly with Heat Protection
Each hose assembly features a PTFE inner lining surrounded by a tightly woven stainless steel braid and a protective black cover to fend off abrasion from chassis edges and headers. The high-pressure hoses resist collapse under boost and maintain a stable internal diameter, ensuring steady flow even when fluid temperature rises. Chemical resilience of the PTFE core keeps the material intact when exposed to transmission additives or cleaning agents. The outer cover also acts as an insulator against radiant heat, safeguarding the braid and core in hot engine bays. Together, these layers deliver a resilient hose that safeguards coolant integrity and minimizes flow restriction over time.
Leak Resistance via CNC Machined Fittings
All fittings are manufactured to exact thread and sealing surface tolerances on precision machining centers, resulting in connections that hold full circuit pressure without seepage. This level of accuracy prevents microscopic gaps that could lead to fluid leaks when the system is heated and pressurized. Secure engagement of the fittings also resists loosening from vibration or expansion cycles, reducing the need for frequent inspections. With reliable sealing in place, clutch pack pressure remains consistent for crisp, repeatable shifts. The robust fittings contribute to lower maintenance demands and peace of mind during extended track sessions or spirited street use.
Strategic Hose Routing for Optimal Thermal Management
The kit's preconfigured hose lengths and angles are designed to clear hot exhaust manifolds, frame rails, and sharp components, minimizing the risk of chafing or heat soak. By avoiding tight bends, fluid flows freely, reducing line resistance and helping maintain lower operating temperatures under sustained runs. Proper clearance prevents hoses from rubbing against engine bay structures, eliminating a common source of premature wear. This thoughtful layout also enhances service access, making visual inspection and routine maintenance faster. Overall, precise routing supports consistent cooling performance and helps preserve transmission integrity in demanding swap applications.
