Np231 issue

I have a 93 4.0 with the np231. Got stuck in a sticky situation and flooded the tranny with water. So I proceeded to flush it until it was completely out, issue is, when I'm in 4 wheel for a period of time or stress it a bit, it whines very loud, to be more specific ( makes the same whiring noise as if you were going in reverse with a manual trans.) is the t-case gonna go or do I have time to save it and what do I do?

Did you flush the tcase as well? They don't, or shouldn't, share fluid.

I also need to know how I can figure out what spline I have, it's the 231 that connects to the 42re trans.

23 spline outer

Tcase has two 30mm plug bolts on the tcase. One to fill one to empty. Easy peasy
