97-98 Transfer Case

Am I correct in saying that the manual and sutomatic transmissions in the 97-98 TJ's used the same transfer case? I was looking online and could only find the one transfer case model for the both transmissions.

You are correct, it was the NP231J. It was used in a lot more years.

You just have to get the right spline count on the shaft

To be honest, I'm not 100% sure. I do they that the NP had different spline counts(I just don't know what went with what).

James, the transfer case's input shaft diameter (spline count) and length varies by the type of transmission it is bolted to.

Your conversion from a manual transmission to the 32RH 3-speed automatic for your '97 TJ means your transfer case input shaft will be too short to seal the new automatic transmission's output shaft which means the new automatic transmission will leak ATF like a sieve. There is an easy fix for that which involves installing an extended output shaft seal into the new automatic transmission that will effectively seal it without any additional modification needed at the transfer case. Just seat it into the rear of the new automatic transmission before you install it and life will be good. The old rear seal can be removed with a pair of pliers which is easily done.

The extended output shaft seal for your new automatic transmission is available from http://www.teraflex.biz/automatic-seal-extension.html
