    Helpful Notes

    • Manual IDs: 98.5–02 trucks may have NV4500 (5-spd) or NV5600 (6-spd) — confirm by shifter pattern/VIN, then shop the correct clutch and hydraulics.
    • Cooling matters: Deep pans + auxiliary coolers dramatically help 47RE life when towing or tuned.
    • Lines & leaks: Replace aged OE hardlines and consider a heat-exchanger bypass when appropriate.
    • Tech rules: Competition use often requires SFI-approved flexplates and documented hardware — check your sanctioning body.

    Frequently Asked Questions

    What’s the best first upgrade for a towing 47RE?

    Start with a quality low-stall converter, a tow-calibrated valve body, and improved cooling via cooler/line kits.

    Which manual clutch should I choose — NV4500 vs. NV5600?

    Pick by transmission model and use. See NV4500 clutch kits for 5-speed trucks and NV5600 clutch kits (incl. Valair dual disc) for 6-speeds.

    Do deep pans and auxiliary coolers really help 47RE longevity?

    Yes — more fluid and better heat rejection reduce thermal stress. See Mag-Hytec 727-D and BD XTRUDE cooler.

    What transfer case fits my 4x4 second-gen?

    Most 98.5–02 4x4 trucks use NP241 variants. We carry 241DHD/DLD parts, complete CPP heavy-duty cases, and Zumbrota remans.

    Any quick-shift options for manuals?

    Yes — BD’s NV4500 and NV5600 short-shift kits tighten throws.
