4cyltoy

He took the nada value and showed me. It was $6000. He said $4500 was the lowest. Should I pass on it then? Its 2wd and I have to convert it or I won't make it through winter. So that's even more $$ ill need to put into it

$4500. It spent its entire life in florida. It is super clean. Ran a carfax and everything is spot on. 3 owners. Even have access to everything I need for 4wd conversion. But that oil covered block scares me alittle. But it is 25 years old. Only 86xxx miles too

Buying a 89 pioneer. It ran good. However, it had almost like a whoosh noise when you would hit the gas...almost like a vacuum leak but it didnt whistle just a whoosh noise. Coolant was clean. Dipstick looked fine and was oil color not milky, but it felt thin..sorta had the consistency of water..figure it really needs an oil change. But no noises. Alittle hard to start, had to give a little gas. H doesn't run it but once a week. My main issue is the entire passenger side of the block is caked in oil. The valve cover gasket is definitely leaking and likely the oil pan. Both were sealed previously with orange silicone. Is there something else that I should look at closer or be worried about before I bite the bullet?

So i will need the flywheel and crank sensor from the 90 xj (ax15). If it is a 91+ will i need the tcu?

I'm going with the Novak cable when I do my 4wd swap. Might want to look into it if you use 4wd often

Well ive done some research and I think I found what I need locally. 1990's xj AX-15 (smaller input shaft) with the np231 and a hp30. I think I'm going to stick with the internal slave for now to get me through winter, and then switch the bellhousing to accommodate an external. Glad I found this because it should be a basic swap plug and play. Sound about right?

Anything new to update? BA build

Anybody have any write ups for 2wd to 4wd swap?

:thumbsup: I was also told that the wiring harness (tcu I guess?) would not work between the two. Sounds like finding a pre 1996 Xj as a donor will be the best scenario...

What are CP's?

Will a 2002 wrangler drivetrain (nv3550 & np231) bolt to a 1989 comanche? Both are 4.0l's. (Converting 89 to 4wd) I have a 2002 donor wrangler so i have access to all parts (axle, driveshafts, bellhousing, etc.) I tried searching but get confused with all the different years that will and won't work, or what i need for certain years.. Thanks, Kody

Awesome job man!

Are the tcu's different for manuals and automatics? It was originally a manual (4 speed I believe) and he swapped in a 1988 cherokee automatic (aw4) and 4.0l. He said the wiring harness didnt have the plugs for the tcu so he never hooked it up

Everything on the truck is in good shape. New lift with xj axles. Interior is rough but not a big deal. Only issue is the auto tranny. I don't mind buying the tcu and tps to get the tranny to work correctly. Only thing that sux is it has to be manually shifted with no tachometer. Good thing ive driven manuals my whole life so I know when to shift gears.

Then I guess the tcu isnt there or its not hooked up. Can one be purchased and is it plug and play? Sorry for all the newb questions. Just trying to see if its worth the $3500 he wants and I don't want to have a bunch of issues.

The owner said he removed the stock ax5 and replaced with the automatic. It has to he shifted manually because the tcu doesn't recognize the automatic. Sound consistent? Any way to fix the issue?

So is it a trial and error type deal? No exact answer? I just wanna swap the auto to a manual. What ever is the easiest and cheapest route I have access to a nv3550 locally so I will go that route if I know exactly what I need. The truck itself is in good condition so the auto tranny issue does not scare me. Winter is approaching and need it swapped before then

Wasn't sure if they changed the engine between 88 and 00 though. Just because its a 4.0 doesn't mean it will bolt up. But what do I know, thats why I'm here

Looking at a 1987 MJ with 1988 XJ drivetrain. Runs fine but the automatic tranny has to be shifted through gears manually. It has 175k miles on the xj parts and I'm looking to swap them out. My buddy has a 2002 wrangler that he totalled and I can buy the drivetrain off him...will a 2002 engine/5 speed/transfer case bolt into the mj? If not, what manual transmissions will bolt to the 88 xj 4.0? I was told it had to be 1996 and older Help needed asap! Thanks Kody
