Ok so run down... I have a 96 xj with an ax-15 in it... I wanna swap everything outta my 97 into the 96...an concern I have is swapping my aw4 into the 96. What all is needed? Change some wiring and tcm? Thanks for the help guys.

You need PCM too. With all the differences you're looking at swapping literally the entire drive train and fuel system.

Is it possible to just swap the trans? The 96 already has motor in it...

No. You need an automatic PCM as well as TCU, which require wiring harnesses, and due to differences in sensors and the fuel system between 1996 and 1997 you need to swap those over as well so the PCM will work.

The AW4 is shifted electronically (using solenoids) in forward ranges - so you can fab up a shifter for it.

You can find a "truth table" for the solenoids/gear range set online. If not, let us know and I'm sure one of us can dig a copy out for you.

Cool thanks! I think I'll just fab up a shifter then! They make any aftermarket shifters out there?

I've heard of a few, but I don't recall which ones are still made. You good with electronics?

You honestly probably only need the AW4 tcu. It is on the CCD buss but I have been sucessful in getting a 98-99(?) TCU to run in a 92 (without a connection to the ECU/PCM). As long as the TCU has TPS, Brake switch, Input/output speed sensors (the ones on the AW4, not the transfer case) and NSS, along with all three solenoids, you should be golden.

I would go to Pirate 4X4 Cherokee section and do a search, they have a lot more info on AW4 swaps. XJ Talk has some good info too.

On the shifter amigo, look on page two of this forum under 87 XJ with downhill problems. Running a new AW4 and installed a RAD Rail II shifter and its the shit... Down hill engine braking with your AW4 is nearly null. This was a huge issue for me so, if you need anything on this, happy to help.

Dude I'm like an hours drive away and I'd rather have a manual trans.
Want to trade jeeps?
Probably easier...
