found a 231 transfer case with a sye but it was from a 4 banger-what would I need to do to convert to a ax15 besides replace the input shaft?

What vehicle are you putting an np231 in? A jeep I'm presuming because of the tranny, you realize that there are many other better TCases you can swap in, right?

If yours blew up and you need a quick fix I guess it might be worth it...but still.


And yes I don't think you have to do anything other than change the input shaft.

Swap the input gear, it's easy, and will give you a good look at the internal condiditon of the case. Check the year before ordering the right input gear or getting one, some different combinations out there, '95 4cyl's used a different planetary set, not better or worse, just different, gotta love that Big Three automaker logic.
