I have a bad transfer case that doesn’t work in 4 high and slips in 4 low. I plan on putting a new one in and was gonna go to the junkyard to get the same one which is 231 j. When I got get a new one would I have to make sure the splines are the same for the drive shaft I have or could I just throw it in it and ride? Also any recommendations on what to do and what not to do when changing it?

Ok so I have an 89 jeep comanche 2wd with the 4.0 inline 6 automatic trans. I am thinking of buying this 86 jeep comanche 4wd with Gm 2.8l v6 automatic trans! Will the transfer out of that bolt up to my tans or no!

Hello everyone! I joined the Comanche Club last week when I purchased an '88 Comanche. She's a beauty. But I'm having an issue that I can't explain. When it's in 2wd, it goes great. But when I put it in 4wd, the rear driver side wheel seems to move slower than the rest, and just skids along. It almost looks like it is trying to go backwards. Everything that I can think of that would explain it, would also manifest in 2wd. So I'm super confused. Any thoughts?

Instilling the Novak Cable shifter on an AX-15/NP242 combo I was in need of a new transfer case linkage setup after I replaced my BA-10/5 & NP231 with an AX-15 & NP242. I purchased the Novak Cable Shifter Kit for$195.85 shipped from Novak-Adapt.com. If you don't want to spend nearly $200 on a cable shifter, then take a look at THIS DIY Linkage, I rediscovered it after I ordered my Novak kit. Before I installed my kit I read over Flint54's install thread. I did not do all the modifications he did, such as to the shift gate. I don't know if Novak changed the kit between the time Flint54's installed his kit and I bought mine. The install took about 2 hours. A second person may be needed during the install. I did not need to remove the cross member or lower the transmission to install this kit, however it would have made things simpler. This kit is not exactly "bolt on" if you have a NP242 like me, some modification may be required. If you had Rhino liner sprayed in the cab you may soon regret it as I did. Keep in mind this is for General Instruction. This is how I did the install. This install was on a 1988 Jeep Comanche, 4.0 I6, AX-15, NP242. Also note my MJ does not have all the factory sized bolts as some have been replaced over the years, I may give a bolt size that is different from factory. Tools Required: Saftey Glasses Gloves Box Cutter (If you have Bed liner in the cab) Wrenches (8mm, 10mm, 13mm, 15mm, 17mm, 1/4, 1/2, 9/16, 15/16, these are what I used) Allen wrenchs Drill Needle nosed plyers Floor Jack (if you decide to remove the crossmember) Start by blocking off the tires and setting the parking break. The Jeep may need to be shifted into neutral during the install. Here are the parts in the Kit: Body side bracket, Transmission bracket, Shifter cable, and a bag containing 4 Allen head bolts, transfer case lever, ball joint of some type, and a clevis yoke. If you haven't already remove the front drive shaft. Use 8mm Socket or wrench to remove the bolts on the front diff yoke and 1/2 wrench for the transfer case yoke bolts. Removed was the body side linkage bracket. It is located on the driver's side of the transmission tunnel. I had the joy of removing bed liner from the bolts holding the body side bracket on. Its a PITA getting that stuff off. Use a 10mm wrench or socket to remove the bolts. After all the bolts are removed the bracket should fall off. I had to use a wrench to pry the linkage bracket from the shifter bushing. I then used a knife to remove the Bushing it self. Installing the new Novak body bracket did not go on as smoothly as I would have liked. I also needed a second person to put the bolts on while I held the bracket in place. Use an Allen Wrench (sorry not sure what size) to install the body mount. Not all the holes lined up properly, but it did not take much to fix the problem. Next I moved on to the Transfer case lever. Use a 9/16 wrench to remove it. There are some Differences between the stock lever and the Novak lever. As in Flint54's thread I later discovered I needed to add a new hole to the Novak lever. I used a drill bit the same size as the hole... Sorry I don't know what size it is. Before you copy my placement please read THIS thread by Flint54. But After I had everything together I guessed where it needed to be based on the placement of the clevis yoke... The new hole placement between My TC lever and Flint54's lever seem to be about the same. Reinstall the Transfer case lever using the 9/16 wrench or socket. These two bolts will need to be removed with a 9/16 wrench. (I did not have any of the AX-15 linkage brackets.) Place the bracket on the Transfer case studs and replace the bolts. I attached the Cable as instructed in Flint54's install thread. Note: My cable did not line up directly to the Handle lever and Transfer case lever. Both cables are adjusted by two 15/16 nuts. Like in Flint54's Install both cables are installed as to where the aft bolt just has full thread engagement. This picture shows the Transmission mount adjustment. This picture shows the body mount adjustment. Here are how the two ends attach to the handle and transfer case levers. Handle Lever Transfer case Lever Reattach front drive shaft... Now everything should be hooked up. Thus far the biggest difference between My install and Flint54's is the shift gate. I currently have the 231 gate on the truck, I have a 242 gate somewhere I just need to locate it..

My new to me 2.5 liter 5 speed 1986 (edited,sorry, not an 85) Comanche X won't go into 4 wheel drive. The are no noises from the Transfer case, it does engage low range, but does not drive the front wheels. A couple times I got a neutral in 4 low, but other times it engages low but does not drive the front axle. There is no indication in the dash as to if it is in four wheel drive. I assume the indicator would be on the right light cluster where the up shift light is. I have read a bit about the vacuum lines having something to do with engaging the front axle. I have searched this forum and else where and have not found a good guide on the subject. I have not figured out if I have an NP 231 or NV 231 transfer case, or what the difference is.

I am getting ready to install my Novak Cable shifter for the transfer case. The instructions say to remove the transmission side linkage mount and re use the bolts. However, my AX-15 did not come with the TC shifter linkage or any mounting hardware. the black and white pictures in the instructions offer very little help. So I am not sure how or where exactly it should mount.. Also what size bolts are used for the transmission side linkage bracket? Thanks

I upgraded from my pugeot to my aisin without issue, except now the transfer case linkage is out of place by an inch and a half or so (seems the entire bracket that's bolted to the body is too far forward)? Am I the only one with this problem, or have others dealt with it, and if so how?

Just got a '92 NP242J out of a '92 4.0 HO, automatic. What I want to put it into: 1990 4.0 AX15. Will I have to switch out the shaft? I believe it's a 23 spline, I'm just not sure about the length.

I got a 5spd peugeot trans and the adapter housing between the trans and t case a bearing broke i need help locating part numbers or size of bearing cause mine was destroyed pictures of bearing would help to

I'm from Utica, Michigan and looking to do a 4wd conversion on my 1989 MJ. Would like to get: (all parts need to be 1991 or older) Aw-4 Automatic Transmission 4x4 Transfer Case Front driveshaft Rear driveshaft (MJ only) Front axle (D30) All these parts expect rear driveshaft can be from an XJ. PM me for any offers. Thanks! :thumbsup:

Hey guys, I was wondering if I could take a 1985 AM207 off an automatic cherokee, and put in on either a 1990 ax-15 (and if possible, is it worth it), or on a 1987 pukey. Also, if it could be done, and is worth it (meaning it's not a POS), would I have to change DS length? Thx guys. Oh, PS, how do you tell what year a transmission is? Thx

Hi guys, so here's the deal. I have a 1990 AX15 with a bad NP231 (chain broke, cracked the case, etc). I also have a 1987 BA10 with a good NP231, but the tranny itself is bad. So, what does it take to put the good NP231 from the French POS onto the good AX15?
