    Don't let leaking transmission lines sideline your 2017-2019 GM 6.6L Duramax L5P. The Fleece FPE-TL-L5P-1719 Heavy Duty Transmission Cooler Lines are engineered to be the ultimate replacement for your old, failing factory lines. This comprehensive kit provides a complete set of robust, flexible lines that not only solve your current leak issues but also boost performance. Their increased diameter and superior design ensure better flow and enhanced cooling for your transmission, helping to protect it from overheating and wear.


    • 5/8" Diameter Hose: The increased diameter over stock lines improves overall flow, which helps your transmission run cooler and more efficiently.
    • Burst-Proof Hose Wrap: A heavy-duty wrap provides superior protection against heat and abrasion, safeguarding the lines against future failures.
    • Complete Kit: This is the most complete replacement kit available, including three transmission lines with AN fittings, six O-ring to AN fittings, and all the necessary clamps and cable ties for a clean and secure installation.
    • High-Quality Fittings: The kit comes with 7/8"-14 O-ring to -10AN fittings for a leak-free seal and a professional-grade look.

    By upgrading to the Fleece Heavy Duty Transmission Cooler Lines, you're not just fixing a leak; you're investing in the longevity and performance of your truck's transmission. These lines are built to handle the demands of your Duramax, providing a reliable and durable solution that far surpasses the factory components. With a 1-year warranty, you can have confidence that you're installing a top-tier product. Please note, this kit is not for use on Cab and Chassis applications.
