Optimized Cooling for GM 6L80E to 10L90E Transmissions

Achieve consistent leak-free coolant flow under intense driving pressures with braided stainless steel hoses and a billet transmission manifold engineered for peak reliability in LS applications. Precision engineered fittings ensure seamless integration with GM 6L80E, 6L90E, 8L90E and 10L90E transmissions, offering hassle free installation without modifications while protecting against overheating and extending transmission life.

LS Engine Transmission Cooler Line Kit for 6L80E to 10L90E

Swapping a 6L80E or 10L90E into an LS chassis often exposes the factory cooler lines to tight bends and heat sources, which can starve the system and promote high fluid temperatures. This Transmission Cooler Line Kit tackles that problem with a billet aluminum manifold that bolts to the tail housing and stainless steel braided hoses sized for consistent flow. By routing the high-pressure hoses away from exhaust headers and sharp frame rails, it maintains steady transmission temperatures during spirited driving.

Billet Aluminum Manifold Optimizes Cooler Circuit Path

The billet aluminum manifold installs directly to the transmission tail housing without any need for drilling or welding, preserving the integrity of the case. Internal flow passages are precision contoured by CNC machining to reduce turbulence and ensure even fluid distribution as it enters the cooler loop. This design maintains consistent pressure and avoids hotspots that can accelerate fluid degradation under hard driving. By aligning with factory port positions, it also cuts installation time and reduces fitment errors that can lead to leaks.

Stainless Steel Braided Hoses Resist Heat and Abrasion

Each hose features a smooth PTFE inner liner wrapped in a tightly woven stainless steel braid that withstands high pressure and repeated temperature swings. The rugged outer cover shields the core from contact with exhaust pipes and sharp frame rails, preventing wear and fluid loss. This construction also resists chemical exposure and radiant heat, so the lines maintain shape and pressure rating over thousands of miles. The result is steady transmission fluid flow that protects internal gears during aggressive shifting.

CNC Machined Fittings Provide Leak Free Seals

Precision CNC machining ensures each fitting meets exact thread form and sealing surface tolerances, eliminating gaps that could allow fluid seepage. By holding full circuit pressure, these fittings protect clutch packs and bearings inside the transmission from heat damage caused by low fluid levels. Their reliable sealing performance also reduces the need for routine maintenance checks, allowing drivers to focus on performance rather than stops for repairs. The outcome is a cooling loop that stays fully sealed and efficient under all operating conditions.

Custom Fit for GM 6L80E Through 10L90E Transmission Swaps

This kit is engineered specifically for GM 6L80E, 6L90E, 8L90E and 10L90E transmissions, matching each port location to avoid sharp bends that restrict flow. By routing hoses away from heat sources and abrasive surfaces, it helps maintain lower fluid temperatures during spirited driving. The one piece manifold and matched hose lengths save installation time and reduce the guesswork that can lead to leaks or kinks. Together, these design choices extend transmission life and support consistent performance under heavy loads.

This well-engineered kit delivers consistent cooling efficiency for your LS transmission swap.
