Here's the story: I have an '89 XJ. The stock transfer case is a NP231. I bought a wrecked XJ and put the motor and tranny/transfer case in mine. It has a NP242, which I understand is better?
Anyway, the front seal on the tranny is now leaking and it slips sometimes. I was going to put the original transmission back in, but with the NP242. My question is how hard is it to swap the transfer case? Is there a gasket or just sealant? If there's a gasket, would Autozone/O'reily's carry it?
I also noticed that the wiring is different for each transfer case. the 231 has two electric plugs and a three-pronged vacuum plug. The 242 only has one electric plug. Will I have to do any rewiring or anything?
If anyone has done this swap or knows what I need to do, your help will be greatly appreciated. Peace
