4L80E Transmission Cooler Line Kit for LS Engine Swaps
When adapting an LS powerplant to a classic chassis controlling transmission temperature on a 4L80E is critical and this Transmission Cooler Line Kit - 4L80E delivers the precise fluid routing needed. Built with stainless steel braided hoses that resist heat soak and road debris these lines hold up to abrasion while fitting neatly in compact engine bays. Precision machined fittings ensure a leak-proof seal against both transmission and radiator ports so vibration and thermal cycles do not compromise fluid integrity over time. This direct fit kit covers 4L80E and 4L85E transmissions with a streamlined layout that reduces sharp bends and simplifies installation for towing or track use.
Stainless Steel Braid Construction for Enhanced Durability
The braided steel sheath encasing each hose acts as a protective barrier against engine heat and road debris, preventing abrasion and maintaining core integrity even under pressure spikes. This sturdy layer preserves consistent wall thickness and resists bulging when the system is under load. In tight engine bays, the braid also shields the hose from contact with sharp surfaces and moving parts. Installers benefit from its natural flexibility, which makes precise routing around brackets straightforward. The result is a long service life that supports reliable performance over many heat cycles.
Precision Machined Fittings for Reliable Sealing
Each fitting is crafted through CNC machining to deliver uniform contact surfaces that match transmission and radiator ports with exacting tolerance. This precision ensures a secure seal that resists loosening from vibration during hard acceleration or heavy towing. When proper torque is applied, the metal surfaces compress sealing gaskets without damaging them, maintaining consistent pressure inside the lines. This approach minimizes the chance of fluid loss and air ingress during thermal cycling. Drivers experience stable fluid levels and crisp shift feel even under demanding conditions.
Optimized Line Routing for Improved Thermal Management
The layout of these cooler lines is engineered to minimize sharp bends and prevent flow disruption, ensuring coolant moves smoothly between the transmission and radiator. By reducing turbulence and hotspots, the system maximizes heat transfer efficiency, which is vital when towing heavy loads or driving on a race circuit. Consistent fluid flow helps maintain optimal operating temperature, extending the life of torque converter components. The tidy arrangement also keeps hoses clear of exhaust manifolds and suspension parts. Visual appeal under the hood is improved thanks to the neat and purposeful pathway.
Complete Kit Configuration for Streamlined Installation
This package includes each high pressure hose along with a complete set of fittings and seals, so there is no need to source additional adapters or connectors. Builders will find that factory style ports and threads align directly with 4L80E and 4L85E transmissions and most radiators. Providing the correct components in one kit reduces the risk of mismatched parts or assembly errors. Technicians can install the cooling plumbing quickly and accurately, saving valuable shop or garage time. With the cooling lines in place, focus shifts to final calibration and testing with confidence in the system integrity.
Engineered for a precise fit and lasting performance in your LS swap.
