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.
