jimoshel Posted August 20, 2012 Share Posted August 20, 2012 Picked up a '98 WJ, or is that a ZJ? 4.0, auto. Anyway the trannys bad. I have a '98 WJ, or is that a ZJ, 5.2, auto. Can I just swap the 44RE for the bad 42RE or is there something to look out for? I also have a '94XJ with a 4.0 and 42RE. Would that work? I prefer to use the 44 because I understand they 're stronger, according to the results I got from search. I will be keeping the transfer cases with their transmissions. :dunno: Link to comment Share on other sites More sharing options...
Alexia Posted August 20, 2012 Share Posted August 20, 2012 Your 1994 XJ has an AW4 transmission.(If it was a 2.5L it would have the 30RH transmission.) 1998 was the last year for the ZJ. An AW4 will work in a ZJ, but it will also require swapping the main PCM out for a manual transmission version. If you are trying to put a 42RE/42RLE/44RE/44RH into a XJ, forget it. Their TCM does not work independently of the PCM. Link to comment Share on other sites More sharing options...
jimoshel Posted August 20, 2012 Author Share Posted August 20, 2012 It is not a AW4. I can recognize them. It is a square , rectangular shaped pan like the later autos.Not ruling out the possibility of a PO swapping something out.I am going to try and put a 44RE into a 98 ZJ.
