LS Transmission Cooler Line Kit for 4L60E Swaps
Swapping an LS powerplant into a chassis equipped with a 4L60E transmission often leads to fluid overheating without proper cooling lines. This Transmission Cooler Line kit - 4L60E uses stainless steel braided hoses and precision machined fittings that seal directly to the transmission case without adapters or trimming. Mounting brackets align with common LS swap locations so the hoses stay clear of frame rails and shroud panels, ensuring consistent fluid flow and temperature control from day one.
Universal Compatibility with GM Transmission Models
This kit is engineered to work seamlessly with Power Glide, TH350, TH400, 200R4, 4L60E, and 4L70E units, making it a versatile choice for a range of LS swap applications. By standardizing hose lengths and fitting orientations around common bellhousing patterns, it eliminates the need to source multiple plumbing solutions for different gearboxes. Integrators benefit from fewer custom cuts and no guesswork when matching line ends to transmission ports. The result is a single solution that streamlines parts management and reduces downtime in the shop.
Stainless Steel Braided Hose Durability
The core hoses feature a multi-layer stainless steel braid over a reinforced fluid tube, providing exceptional resistance to abrasion, heat and corrosive fluids in the engine bay. An outer black covering further shields the assembly from oil splatter, road debris and UV exposure. This robust construction maintains consistent internal diameter under pressure, preventing swelling that can restrict fluid flow. In daily driving or spirited runs, the lines hold shape and integrity, ensuring reliable performance for years.
Precision Machined Fittings for Leak-Free Sealing
Every fitting is CNC cut from corrosion-resistant alloy to match 4L60E case ports without the need for adapters or trimming. Integrated o-ring grooves and smooth sealing surfaces deliver a leak-free seal under high pump pressures. This exact-fit approach eliminates common plumbing errors and reduces the risk of seepage over time. Technicians can trust that connections will remain tight through repeated thermal cycles and vibration.
Optimized Cooling for Transmission Health
By routing fluid through an external cooler before returning it to the transmission, the kit maintains stable operating temperatures under all load conditions. Cooler fluid extends clutch pack life and preserves hydraulic integrity for crisp, consistent shifts. This thermal management strategy supports towing, daily commuting and track duty without risking seal failures or pressure loss. Ultimately, it protects your investment and keeps shift quality precise mile after mile.
Engineered for a precise fit and lasting performance.
