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 Extreme Duty Bar-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.
