Transmission Cooler Line Kit for LS 4L60E Swap
When you install an LS power plant with a 4L60E transmission into a standard chassis maintaining correct fluid temperatures becomes a critical concern that helps protect clutch packs and internal seals from premature wear. This Transmission Cooler Line Kit routes fluid through an external cooler using precision machined fittings and stainless steel braided hoses that attach directly to the transmission case without adapters or trimming. By keeping lines clear of frame rails and shroud panels the system ensures stable gear shifts and extended component life under demanding driving conditions. Each hose length and mounting bracket is pre measured to align with standard LS swap points so installers avoid custom trimming or extra parts sourcing.
Robust Stainless Steel Braided Hose Construction
The hoses in this kit feature a multi-layer stainless steel braid surrounding a reinforced inner tube, delivering exceptional resistance to abrasion and chemical attack in the engine bay. An outer black cover shields each line from oil spray, gravel, and ultraviolet exposure without adding excessive bulk. Under elevated fluid pressures the braided design preserves its internal shape, preventing expansion or collapse that could impede flow. This rugged assembly ensures that lines retain their integrity even during repeated road vibration and heat cycles. In both daily use and spirited driving scenarios, these hoses stand up to harsh conditions and safeguard transmission performance over many seasons of service.
Precision Machined Alloy Fittings for Secure Sealing
Each fitting is CNC machined from a corrosion-resistant aluminum alloy and tailored to match 4L60E case ports exactly, eliminating the need for adapters or field trimming. Integrated o-ring grooves and smooth sealing faces produce a reliable leak free connection under high pump pressures and varying temperatures. This exact-fit approach removes common alignment guesswork, allowing technicians to install lines quickly with confidence. The uniform tolerances maintained by precision machining also minimize the risk of seal failure caused by uneven surfaces or misalignment. Service technicians benefit from predictable results that hold up through vibration and repeated thermal cycles.
Advanced External Cooler Integration for Stable Temperatures
By routing transmission fluid through an external cooler before it returns to the gearbox, this kit delivers consistent thermal management even under heavy towing or track use. Cooler fluid extends the life of clutch packs, preserves hydraulic integrity, and helps maintain crisp, consistent shift feel. The optimized hose lengths and fitting angles keep fluid lines clear of obstacles such as frame rails and shroud panels, ensuring unrestricted flow to the cooler core. This careful routing prevents heat soak and reduces the risk of fluid breakdown during extended highway runs or demanding off-road driving. The result is reliable performance and peace of mind in any driving condition.
Complete Kit Layout Ensuring a Streamlined Installation
This all-in-one solution arrives with hoses, fittings, and mounting brackets pre-measured for common LS swap points, removing the need for custom hose runs or additional parts sourcing. Installers save time by simply following labeled hose paths and bolt-on bracket locations that align with standard chassis mounting holes. Since each component is engineered to fit without trimming, technicians achieve a clean, professional appearance and consistent fitment each time. The comprehensive design helps avoid installation errors and simplifies maintenance access for future service. From initial mock-up to final torque checks, the kit delivers a seamless installation experience.
