kinda bringin this back from the dead but im in the middle of this swap at the moment and figure ill throw my input in for those that may be interested
i assume his reason for advising against the AX15/NP242 combo is because the 242 acts like a differential with clutches that allow slipping in full-time mode which you dont notice with the automatic but from what ive read the slop is pretty noticeable when shifting in a 5spd.....hope that made sense
for those interested in the AW4/NP242 > AX15/NP231 i have a thread here and other forums that ive decided to post my findings and info to hopefully help those thinking about venture down this road especially on a renix era cherokee

If I had a 1995 xj auto because no manuals were imported into Australia what could I do to make it manual can i keep the engine and ecu and put a 5 speed wrangler gearbox could that work? Or just straight swap a wrangler engine and gearbox ecu?? And yes I'm new to this site need some help on ideas

I think the ECU on a 95 is only for the engine, so its independent from the trans, meaning it could have a T-56 behind it and it wouldnt know the difference.
you would have to sort out whether or not its internal or external slave and get the appropriate "accessories" like pedals, master cylinder etcetera.
I dont think it would be too bad, however, your statement saying that none were imported means you could have a parts shortage and be needing to import certain stuff

captain pretty much nailed it, also the wrangler[YJ] 5spd is clocked 10* upward compared the XJ 5spd so you will either have to redrill the tail adapter on the trans or get a BFH and wail on your floor boards for clearance.
not positive on the computer aspect of it as i believe 95 is OBD1 compared to my jeep which is preOBD so computer doesnt know the difference as long as i have the correct sensors for a manual.
my initial post covers almost everything that is needed, as for a parts source thats something you will need to figure out for yourself....if you can get the trans and transfercase from a wrangler that will work, you will just need to redrill the clocking ring, there is plenty of write ups on doing such, the rest of the parts you would probly have to go ebay or something.
EDIT : ok my bad if above your thinking WTF is he talking about with regards to initial post...i thought this was my AW4>AX15 thread. https://www.cherokeeforum.com/f67/aw4-ax15-swap-115539/

what about trying the New Venture Gear NV3550 found in the 2000-2001 XJ's ?
I'm looking to swap in a diesel engine, and it requires a manual transmission, so i am interested in this thread...

I have successfully done a auto->manual swap in my 92' XJ.
I was fortunate enough to get a great deal on a AX-15 and a complete pedal assembly along with a clutch master cylinder and a flywheel.
This conversion was actually very simple compared to what I was expecting it to be. The only things that I had to change were the flywheel, a 91' flywheel doesn't work in a 92' engine (the notches for the CPS are different). Then the REAL headache was sourcing the pilot bearing. Thanks to Advanced Adapters I was able to get that part.
Everything bolted up like it should and works like it was intended to from the factory.
I would HIGHLY recommend not using a used master cylinder or purchasing a rebuild kit for them. Just buy the braided line from advance adapters, and then buy a plastic master cylinder for a later year Jeep with a manual. Then, you won't have to worry about brake fluid leaking onto your fuese block and causing issues like I have had to deal with.
Other than that, it is worth it, the AX-15 is lighter than that dog-o-matic AW4 is and you can even sell the AW4 to offset some of this conversion costs.
Electrical issues? I have had none with the swap. The ECU is engine only (gotta love OBDI). And I juse cut the two wires and put them together with a butt connector so that it would bypass the park/neutal (No Start) situation.
I am now in the process of trying to find out what is needed to put this setup into my newly aquired 00' XJ Classic with a dog-o-matic in it. The pedal assembly seems to be the big problem. As the AX-15 will bolt up.

i'd be interested in what you come up with, and what it ends up costing. I have an '01 and the AW-4 adapter still requires you to manually shift the gears at this stage, so i'm wondering if what you did would make more sense. I prefer manual transmissions anyways, but they tend to be much harder to find in used vehicles.

If you attempt to do a manual swap in a OBD-II XJ then you will be forced to obtain a PCM/ECU that will be from a OBD-II XJ that had a manual in it. If you do not do this there will be a code that will be kicked, and the light will be on. And you WILL fail emissions if you have to pass them in your state.
Then, there is the issue of finding a pedal assembly. Because, you can take out the one you have, and then with a OBD-I XJ pedal assembly make one assembly that will work. But, it is much easier to just bolt something in. But, good luck finding that assembly! And when you do what will it cost?
Those are the two major problems with a OBD-II XJ auto->manual swap. After you get those parts, you can either use a AX-15 or the NV (5sp or 6sp) manual transmission. Purchases, a clutch kit, flywheel, pilot bushing/bearing, clutch line, clutch master cylinder. And do your swap.
Me personally, at this point. I am not going to follow through with the swap. I got lucky the first time with finding someone that would sell me everything that I needed for the conversion in my 92' XJ. But, for this 00' XJ. There is simply too much more that is involved and will require much more $ than it did with my 92'. And winter is coming, so the last thing I want to be is not in a Jeep during winter.
Good luck though!

Old thread but i did the swap on my 99 xj i bought a 95 xj parts truck it was a fairly simple swap i modded the clutch bracket to work i ran the auto computer for a little bit it would bog out and almost stall when stopping i got a manual ecu and all the problems went away my truck looks like and drives like it was a factory swap no CEL and is a fun time to drive ill tell anyone who does this swap its a lot of little things after you get it driving to ge tit back to factory looks but its worth it
