Is the AW4 actually different for those years? I thought it was just the seperate TCU (integrated with the ECU on later years, not part of the tranny) that made those years easier to swap to other rigs.
The reason I ask is that I've been eyeing an engine/tranny combo for sale out of a 2001 to swap into my '94. If I end up buying the combo I'd have either a '94 or 2001 AW4 tranny left over, but no seperate TCU. I do think I saw a few early AW4 TCUs still in the XJs at the Pick and Pull yard in Mesa (for that matter there may have been complete early AW4s in the yard as well.)
