bellhousing is the hardest to find :( 

I think I can source that pretty easily from ebay or deadjeep, but we'll see!  I was able to source another part of the puzzle earlier this week, a computer from a 91' XJ that came factory with a 4.0 and a manual.  That should just swap in I believe and correct any issues as far as pcm/tcm go.

You shouldnt need to change your PCM at all to run manual. You just need to jump two pins on the NSS plug and rewire the reverse lights for the AX-15 detent ball switch thing.

I know on Renix the Auto computer has a higher idle and 96+ throws a CEL, but I think Torq is right and 91-95 there's no reason to swap computers.


I had read (possibly incorrectly) that the computers for the obd1 systems would have either lower or higher idle issues and that a computer swap would correct this, but maybe it was just for the renix years.  Either way, a guy had done a obd2 swap in his cherokee and gave me the computer for not much more than shipping costs so I'm not too worried about it.  When i get to the point where I actually swap the trans, I'll do a test of both computers and see if there's any change for the community!
