231 Tcase swap
I so I have the AX 5 trans and I have bolted up a np231 for several different reasons but I have run into a problem it seems. Since I have out the new tcase in it has been pissing trans fluid from between the tcase and trans . I have replaced the output shaft seal on the trans a couple times thinking it may have been a bad seal but it still is leaking like crazy >:/ anybody got any ideas? Is the diameter on the tcase different so the seal is not matching up?

The transfer case and transmission have no sealing ability between each other. They're independent units.
So your AX-5 is leaking shortly after you put a new seal in? Fast seal death is usually a sign that the bearing behind it is toast.

The np231 uses atf.
Which are you leaking?

And then confirm that the sealing surface on the output shaft is in good condition.
Also, how did the seals you removed look? Any signs of abrasion or swelling?
I think I recall reading the there might have been different output shaft spline counts in different years. Measure the diameter of the output shaft sealing surface and make sure the seal is designed for that size.
