4L80E Transmission Cooler Line Kit for LS Engine Swaps
When transmission fluid faces extreme heat during aggressive runs the Transmission Cooler Line Kit - 4L80E delivers reliable flow between radiator and 4L80E transmission with stout stainless braided hoses and precision fittings. Each hose resists abrasion and internal pressure to keep coolant moving smoothly and avoid hotspots around the torque converter. Fittings machine to exact tolerances so connections stay leak free through vibration and thermal cycling. By routing coolant along an optimized path under your LS swap this kit ensures stable transmission temperatures under track or towing duty.
Stainless Steel Braided Hose Durability
The stainless steel braid surrounding each hose delivers exceptional abrasion resistance and pressure tolerance, guarding the inner liner against wear from road debris and engine heat. This construction also prevents kinks or bulges when fluid is forced through under load, ensuring consistent flow even during spirited driving or towing. Despite its ruggedness, the assembly retains enough flexibility for precise routing in tight engine bays. The result is a hose that stands up to harsh conditions without compromising transmission cooling performance.
Precision Machined Fittings for Leak Free Connections
Each fitting in the kit is CNC machined to exact tolerances, creating a seamless seal against radiator and transmission ports. This level of precision maintains constant seat pressure on seals, so vibration and temperature changes do not compromise the joint. Once torqued to the proper specification, these connectors prevent fluid loss through thousands of heat cycles and rough road surfaces. By eliminating the risk of leaks, they help preserve consistent transmission temperatures and system reliability.
Optimized Coolant Path to Eliminate Hotspots
The kit's routing strategy minimizes sharp bends and flow disruptions, allowing coolant to move swiftly between the 4L80E transmission and radiator. A smooth path preserves flow rate and maximizes heat transfer, preventing localized temperature spikes around the torque converter. This careful design ensures transmission fluid remains at a stable temperature during track sessions or heavy towing. The outcome is improved component life and consistent performance under sustained stress.
All Inclusive 4L80E Line Kit for Easy Installation
This kit includes every braided hose assembly and fitting needed to connect an LS engine to a 4L80E or 4L85E transmission, so there's no need to hunt for matching parts. By providing purpose-built components, it streamlines the swap process and reduces build time. Installers benefit from a complete, vehicle-ready solution that delivers a clean fit and reliable cooling system right out of the box. The comprehensive approach simplifies your project and ensures a professional result.
Engineered for a precise fit and reliable cooling performance in your LS swap.
