Transmission Cooler Line Kit for LS 6L80E-10L90E Swaps
When you install a 6L80E or 10L90E transmission in an LS chassis, this cooler line kit addresses cramped fluid paths that can lead to slow flow and overheating. It features stainless steel braided hoses paired with precision CNC fittings and a billet aluminum manifold that bolts to the transmission tail housing without any drilling. Protecting lines from abrasion heat and chemical exposure, the routed hoses maintain steady fluid pressure under heavy load and help keep transmission temperatures under control during spirited driving.
Bolt On Billet Manifold Streamlines Installation
The billet aluminum manifold attaches directly to the transmission tail housing without any case modifications, eliminating the need for drilling or custom brackets. Internal flow passages are precision contoured to minimize turbulence and balance fluid distribution before the cooler circuit, ensuring consistent pressure throughout the system. By following the factory port layout, this bolt on solution cuts installation time and reduces the risk of misaligned fittings that can compromise cooling. Technicians benefit from a straightforward mounting process that delivers reliable performance from day one.
Stainless Steel Braided Hoses with PTFE Core Resist Wear
Each hose features a smooth PTFE inner lining wrapped in a dense stainless steel braid that withstands high pressure and repeated temperature cycles. The rugged outer sheath protects against abrasion, chemical exposure, and radiant heat, so the lines maintain shape and pressure rating over thousands of miles. This construction prevents soft spots and swelling, reducing the chance of collapse under load. As a result, transmission fluid flow remains steady even in demanding driving situations.
CNC Machined Fittings Deliver Leak Proof Operation
All fittings are crafted with CNC machining to meet exact thread form and sealing surface tolerances, eliminating seepage at critical junctions. This precision manufacturing preserves full system pressure and prevents fluid loss that can lead to hot spots inside the transmission. By ensuring a tight interface at every connection, these fittings minimize maintenance checks and protect internal components from premature wear. The result is a cooling loop that stays sealed and efficient through rigorous use.
Engineered Fit for GM 6L80E to 10L90E Transmission Conversions
This kit is designed specifically for GM 6L80E, 6L90E, 8L90E, and 10L90E transmissions, matching factory port locations to avoid alignment guesswork. Custom routing keeps hoses free from sharp bends and kinks that can restrict flow under high load, while reducing stress at connection points. Consistent fluid delivery helps prevent overheating during spirited driving and supports cooler operating temperatures over long runs. The precision fit promotes extended transmission life and dependable performance in a variety of chassis applications.
Designed for LS swaps, this kit ensures consistent fluid flow and lasting transmission health.
