4L80E Transmission Cooler Line Kit for LS Engines
Swapping an LS powerplant into your ride puts extra heat into the 4L80E transmission and the Transmission Cooler Line Kit - 4L80E is built to manage it. Wrapped in a stainless steel braid, each hose stands up to engine heat and abrasion while ensuring steady fluid flow even when pressure spikes. Precision engineered fittings deliver a leak proof seal that resists vibration and temperature swings. An optimized coolant path under your LS swap maintains stable transmission temperatures on track or during towing.
Stainless Steel Braided Hose Endurance
Each line in this kit features a stainless steel braid that guards the inner hose against road debris and engine heat. This layer of protection prevents wear and maintains a smooth inner surface, ensuring transmission fluid flows consistently under pressure. The assembly also resists bulging and kinking, so even during heavy towing or spirited road use the cooling circuit remains stable. Installers will appreciate the balance of rugged strength and enough flexibility to navigate tight engine compartments without fuss.
Precision Machining for Reliable Seals
All fittings are CNC machined to strict tolerances for a tight, uniform seat against both radiator and transmission ports. This precision delivers a leak proof connection that stands up to constant vibration and repeated warm‐cool cycles. Once properly torqued, the joints maintain consistent pressure on internal seals so fluid loss is virtually eliminated. The result is peace of mind in knowing your transmission stays cool without unexpected drops in system pressure.
Streamlined Coolant Routing Under LS Swap
The hose layout is designed to minimize sharp turns and flow interruptions, allowing coolant to travel efficiently between the 4L80E transmission and the radiator. By reducing turbulence the system maximizes heat transfer and avoids localized hotspots around the torque converter area. Whether you're hitting the track or towing a heavy trailer, stable fluid temperature supports reliable shift performance and extends component life. The neat routing also helps maintain tidy engine bay aesthetics.
Comprehensive Kit for Simplified Installation
With every high pressure hose and all necessary fittings included, there’s no need to source parts separately. This all inclusive approach cuts down on build time and eliminates the guesswork of matching adapters. Installers benefit from a ready-to-go package that ensures correct fit and reliable cooling right out of the box. The streamlined process delivers professional results and frees you to focus on other aspects of your LS swap project.
Engineered for a precise fit and reliable cooling performance in any LS swap project.
