LS Transmission Cooler Line Kit for 4L60E
When installing an LS engine with a 4L60E transmission in a swap project, maintaining fluid temperature is critical and the Transmission Cooler Line kit for 4L60E addresses this by routing hot transmission fluid to an external cooler. Each assembly features stainless steel braided hoses clad in a polymer guard that resists corrosion and abrasion. Hoses rated for high pressure operate with Power Glide, TH350, TH400, 200R4, 4L60E and 4L70E transmissions. CNC machined aluminum fittings are included for secure, leak free connections to radiator ports, and the complete kit ships with every fitting and hose required so no additional components are needed for a precise installation that protects against overheating.
Compatibility and Engine Integration
The Transmission Cooler Line kit designed specifically for LS engines supports 4L60E and 4L70E units as well as legacy Power Glide, TH350, TH400 and 200R4 transmissions. Integration with MuscleRods mounting systems ensures precise alignment of the cooler lines with existing hardware. This partnership maintains ideal transmission angles and fluid flow without modifications to the frame or engine placement. Builders benefit from a direct fit solution that streamlines assembly and preserves factory clearances.
Durable Hose Construction
Each kit includes high-pressure stainless steel braided hoses wrapped in a sleek black covering that resists heat, abrasion and chemical exposure. This finish stands up to demanding underhood environments and maintains flexibility for routing in tight engine compartments. The braid layer reinforces internal tubing to withstand elevated transmission pressure and prevent hose expansion under load. As a result, fluid delivery remains consistent during hard shifts or towing scenarios.
Enhanced Cooling Efficiency
Efficient transmission cooling is crucial for LS powertrains, where torque output and heat generation can be significant. The carefully sized lines promote rapid heat dissipation and fluid movement through the external cooler. By reducing the temperature of circulating fluid the kit helps preserve internal seal integrity and extends service intervals. Drivers will notice cooler operating temperatures under repeated high torque launches or sustained highway pulls.
Complete Kit and Installation
This comprehensive kit includes all necessary crush washers, fittings and adapters for a turnkey installation. Engineered fittings thread easily into factory cooler ports and provide a secure and leak free connection with common hand tools. Clear instructions guide installers through each step from initial routing to final torque values. Whether updating an existing LS swap or building a fresh muscle car the kit delivers reliable cooling performance without guesswork.
Trust MuscleRods for a reliable LS transmission cooling solution that ensures secure leak free fittings and steady fluid flow in every installation.
