AX15 to Aw4 swap
 

Hello all,
So im entertaining the idea of the swap mostly because i wheeled my buddy's auto and it was the first time i ever drove an auto xj...so between liking it more and my knee on it way out i figured id start gathering the parts....all the research i did either turned up the swap for wranglers or pre 97 .. mine is a 99 and i know the major parts and how to do most of it but i was looking to see if anyone had any advice or if there was any parts on my list im missing.
AW4
crossmember
torque converter/flexplate if not with trans
shifter/bezel/
shifter cables
tcu
Wiring harness?( when i had my motor and trans out last i dont recall there being a plug to disconnect that harness so do i need a full engine/trans harness ?)
also i read something about the shafts on the TC being different but once again nothing about 97-01


thanks for any help guys

yes driveshafts are different lengths, mainly because the AW4 is few inches longer than the ax15.

I also am not sure about full engine/trans harness. But you are spot on everything else

Luckily I have a cv shaft that I picked up when I did the sye that was too long so I'll have that...thanks! I might just have to get my buddy's auto on the lift and see what's going on unless someone else knows

Too bad I don't have time I would give you my AW4 and swap in your 5 Speed. I would love to have a stick in my XJ.

Don't forget to remove the pilot bearing from the crank.

That would be ideal ....it is fun with a 5 speed just not when you have a tricky hillclimb with ruts haha. And yes I know about the pilot bearing thanks... It s not getting done for another few months while I gather parts and a plan... And clean the garage from the last project

I would shop for a wrecked 99 XJ with an AW4 in it and have everything you will need plus extra parts if needed.

That's what I'm trying to do...Only problem is cherokees really started taking off again in the last year by me so everyone thinks they are sitting on a gold mine.

You are going to have to regear or swap axles. The 3.07 gearing won't cut it with the aw4.

Also check to see if your radiator has the transmission cooler and consider adding and extra.

Swapped in 3.55s last year so that's not an issue and I replaced the rad 2 years ago and plugged the cooler lines to keep crap out but I'll probably run a bigger aux cooler instead

I know the name of that tune! Motor in the Jeep...SOB won't quite pull tight to tranny...WTH...bigger hammer ,, new French vocabulary... grunting and sweating! Just remembered the motor came out of a manual XJ! Pry engine and tranny apart just enough to reach pilot bearing, RIP it out with pry bar... motor and tranny slide together like two hot minks in the forest! Mission accomplished... <wiping sweat off forehead as I grab a cold one>

AMAZING

First, Good job bringing back a dead thread.

Second, IDK how this went for him.

Third, Youre in the best position because many people are on the lookout for a 5-speed swap. want to get rid of their auto. Find someone looking for the manual and swap them for their AUTO. All of the necessary parts are available on the other guys rig.

How are your shift points?
 

I just got my AW4 buttoned up and the shifts from 1-2 and 2-3 bog down between shifts. Just replaced my NSS, cleaned my IAC. Any thoughts on correcting this? Also I adjusted my TV cable as directed online.
