Description
Fluidyne Transmission Cooler Line Kit – 2003-2007 Dodge Ram (48RE)
NOT FOR EXTREME DUTY COOLER.
Upgrading to a real transmission cooler? Then don’t choke it out with your factory -6AN lines. This Fluidyne -8AN steel braided line kit is the final piece of the puzzle—built to feed your cooler the flow it needs without restriction.
Wrapped in a high-temp silicone jacket and finished in stealth black, these lines are as tough as they are clean. Designed specifically to pair with the Fluidyne 3rd Gen UPGRADED Stacked Plate Transmission Cooler, it’s a perfect fit for 48RE-equipped trucks that actually get used.
This kit also bypasses the factory heat exchanger—an aging weak link known to fail and cross-contaminate coolant with ATF. Killing two birds. One upgrade.
If you’re gonna cool it, do it right.
