I read the details of the AW4 transmission, but I could not really find out if a ‘96 AW4 2WD transmission would fit a 2001 2WD XJ. Can I swap it or are there a bunch of modifications?
What's the issue with your AW4? The vast majority of the problems are electronic and not mechanical.
You might want to elaborate and/or take pics. Bolts and studs can easily be replaced?
This write-up does not attempt to cover the 2wd editions of the AW4 as thoroughly as the 4wd. The major difference is the addition of another year split - 1995 and earlier 2WD AW4s will have the old style slip yoke and output seal while 1996 and later 2WD AW4s will have the new style slip yoke and output seal, as well as dust slinger. The vehicle speed sensor is also located in the transmission tailhousing. A 2wd AW4 cannot be converted to a 4WD unit without full disassembly as the output shaft is a different length, has 27 splines (to match the slip yoke used on the rear output of 4WD XJ transfer cases) rather than 21 or 23 splines, and includes the 13 tooth worm gear for the VSS or speedo takeoff which would otherwise be in the tailcone of the transfer case.
So if I read this correctly, a '96 2WD tranny would have no issues in an '01 XJ? It says nothing about PCM issues and such.
2WD or 4WD does not matter, the transmission does not even know if it is 4x4 or not.
I don’t believe this is true — I have a 2wd 96 — I cannot simply add a transfer case to my 2wd transmission to make it 4wd
From what I understand 2wd transmissions are physically different than 4wd transmissions
It's not quite that simple but yes you could do it.
No, the trans is the same other than the tailshaft cone.

You misunderstood what i meant. I meant as far as compatible swaps it doesn't matter. Swap in a 2wd trans or a 4wd trans and a t-case, either is compatible.
