Product Description
Build your own rebuild kit for the NP233 / NV233 / NP149 (NP207) transfer case. Electric push-button NP233 only (not lever-shift NP231, not full-time NP136/NP242). Pick the overhaul kit that matches your case, then add only the parts you need.
Build your own NP233 rebuild kit: choose the parts that match the transmission on your bench and leave out what you don't need. This builder has 8 option groups and 21 choices, all optional, so the kit holds only what you pick.
