LS Transmission Cooler Line Kit for 6L80E to 10L90E Engine Swaps
When fitting a 6L80E, 6L90E, 8L90E or 10L90E transmission into an LS chassis, stock cooler hoses often route too close to hot exhaust or tight frame rails, causing heat soak and fluid pressure loss. The Transmission Cooler Line Kit - 6L80E-10L90E addresses this with a billet transmission manifold and stainless steel braided hoses under a protective black cover, delivering reliable and leak proof fluid flow. Precision engineered fittings align exactly with GM ports for tool free installation with no transmission case modifications. This kit includes every radiator connection fitting needed for installation and features rugged construction to maintain fluid temperatures under demanding conditions and support extended transmission lifespan.
Precision Cooling System Design
The Transmission Cooler Line Kit - 6L80E-10L90E utilizes black covered stainless steel braided hoses rated for high pressure to deliver superior fluid transfer under demanding conditions. Precision-engineered fittings create a secure, leak-proof seal at each junction, ensuring consistent transmission fluid flow and safeguarding against pressure drop. The combination of robust hose construction and high-performance cooling capability reduces operating temperatures, which is critical for maintaining torque converter efficiency and protecting clutch packs during sustained towing or track sessions.
Seamless MuscleRods Integration
This kit features a billet transmission manifold that allows for a no-mod installation on GM LS engine platforms. By aligning perfectly with MuscleRods LS mount geometry, it preserves the factory drivetrain angles and secures the proper engine placement relative to the frame. The custom routing reduces the risk of line chafing or pinching, while the dedicated manifold ports eliminate the need for adapters or custom brackets. As a result, installers achieve a clean fit that adheres to original equipment standards and maintains service access to other accessories.
Custom Fitment for Multiple Transmissions
Engineered specifically for 6L80E, 6L90E, 8L90E, and 10L90E transmissions, this line kit matches the stock cooler ports for direct bolt-on assembly. Each hose length and fitting orientation is tailored to the transmission case, ensuring proper clearance and eliminating the guesswork of universal plumbing solutions. This vehicle-specific design not only simplifies installation but also upholds the correct pressure characteristics dictated by each gearbox, enhancing shift feel and safeguarding internal components.
Rugged Construction for Extended Service Life
Built to withstand the rigors of high torque output and aggressive driving scenarios, the Transmission Cooler Line Kit employs a billet aluminum manifold and stainless steel hose assemblies that resist corrosion, heat soak, and physical abrasion. The durable materials and careful engineering reduce maintenance intervals and extend the lifespan of the transmission by keeping fluid temperatures within optimal ranges. For enthusiasts seeking reliable cooling performance under heavy load or spirited driving, this kit delivers both peace of mind and measurable protection against premature wear.
Enjoy precise fluid control and rugged reliability in your LS swap with this billet manifold and braided stainless hoses that require no transmission modification.
