Description

The factory lines were adequate for the 90s, but this kit upgrades to robust -8AN steel braided lines, protected by a high-temp silicone exterior for enhanced durability. The all-black finish provides a clean, stealthy appearance under the hood. Designed to complement the Fluidyne 2nd Gen Transmission Cooler, this setup completely bypasses the stock heat exchanger, mitigating the risk of coolant contaminating the ATF—a common issue leading to failure in 47RH/RE transmissions. This is the cooler line upgrade your transmission needs.
