LS Engine 4L60E Transmission Cooler Line Kit
When installing an LS engine into a chassis matched to a 4L60E transmission, proper fluid cooling is crucial to prevent overheating during demanding use. This Transmission Cooler Line kit - 4L60E routes fluid through an external cooler using precision machined fittings and stainless steel braided hoses that seal directly to the transmission case without adapters or trimming. Mounting brackets align with standard LS swap points to keep lines clear of frame rails and shroud panels for reliable flow and consistent temperature control.
Robust Stainless Steel Braided Hoses for Enduring Performance
The core hoses in this kit feature a multi-layer stainless steel braid over a reinforced fluid tube, delivering exceptional resistance to abrasion, heat and chemical attack in the engine bay. An outer black cover shields the lines from oil splatter, road debris and UV exposure without adding bulk. Even under high fluid pressure the braided construction maintains its internal shape, preventing swelling or collapse that can restrict flow. In daily driving or spirited use, these hoses hold their form and integrity for years of reliable service.
Precision Machined Fittings for Consistent Leak Free Sealing
Each fitting is CNC cut from a corrosion-resistant alloy and engineered to match the 4L60E case ports without any adapters or trimming. Integrated o-ring grooves and perfectly smooth sealing faces ensure a reliable seal under intense pump pressures and thermal expansion cycles. This exact-fit method removes the guesswork common to custom plumbing and virtually eliminates seepage points. Technicians gain confidence that each connection will remain tight through vibration and repeated heat-cool cycles.
Optimized Thermal Management Through External Cooler Integration
By routing transmission fluid through an external cooler before it returns to the gearbox, this kit keeps operating temperatures in check even under heavy loads. Cooler fluid extends the life of clutch packs and preserves hydraulic integrity for crisp, consistent gear changes. This approach protects seals and internal components during towing, track sessions or long highway runs. The result is stable performance and reduced risk of overheating in demanding conditions.
Comprehensive Kit Design for Streamlined LS Swap Installation
Everything needed for a 4L60E transmission cooling install arrives in one package, including black-covered braided hoses, fittings and mounting brackets. Hose lengths and fitting orientations are pre-measured to align with standard LS swap points, keeping lines clear of frame rails and shroud panels without trimming. Installers save time by avoiding custom hose runs or extra parts sourcing. The complete solution delivers a clean, professional installation from start to finish.
Engineered for a precise fit and reliable cooling performance.
