Transmission Cooler Line Kit for LS Engine with 6L80E-10L90E Transmission
Swapping a 6L80E or 10L90E into your LS chassis often leaves stock cooler hoses skirting hot exhaust manifolds and narrow frame openings and driving up fluid heat. This Transmission Cooler Line Kit - 6L80E-10L90E replaces those vulnerable conduits with a billet aluminum manifold at the tail housing coupled to stainless steel braided hoses sheathed in a protective cover. Machined fittings align perfectly with GM port locations to seal under pressure without any transmission case changes. Hose lengths and bend angles are preset to clear headers and chassis points while preserving straight fluid paths for even flow under intense cooling demands.
Precision Billet Manifold for Seamless Transmission Integration
The billet aluminum manifold is CNC machined to match GM 6L80E and 10L90E tail housing port locations exactly, allowing installation without any transmission case modification. This precise fit maintains straight, uniform passages that reduce fluid turbulence and preserve system pressure even under the most demanding shifts. By aligning with original port geometry, the manifold seals consistently to prevent leaks that can compromise clutch pack pressure and shift performance. Even flow distribution helps avoid localized hot spots, reducing thermal stress on internal components and extending service intervals. Its robust construction also resists distortion at high fluid temperatures, ensuring reliable coolant circulation during spirited driving or prolonged track use.
Stainless Steel Braided Hoses Engineered for Heat and Pressure Resistance
The cooler lines feature stainless steel braided hoses over a smooth inner core to withstand extreme pressure and elevated fluid temperatures. A black protective sleeve shields the braided layer from abrasion against frame rails and header pipes, and also reflects radiant heat away from the hose body. Predefined hose lengths and bend angles ensure clearance from hot exhaust surfaces and tight chassis areas, minimizing the need for on site trimming or rerouting. This design maintains an unrestricted flow profile to support efficient heat transfer at all times. As a result, the transmission fluid remains cooler and cleaner under prolonged performance use, which helps protect internal seals and bearings from premature wear.
Precision CNC Machined Fittings Ensure Leak Free Performance
Each fitting is manufactured on multiaxis CNC machining centers to meet exact thread and sealing surface tolerances, providing a secure connection that resists seepage under high pressure and temperature cycles. This accuracy prevents microscopic gaps that could otherwise open when fluid expands under heat, eliminating a common source of leaks in aftermarket installations. The secure engagement of the fittings also resists loosening due to engine vibration or expansion and contraction, reducing maintenance needs. By maintaining consistent hydraulic pressure to the valve body, shift events remain crisp and repeatable even during aggressive driving. End users gain peace of mind and lower service demands thanks to the reliable seal integrity of each connection.
