James and Sugarfoot Posted October 5, 2007 Share Posted October 5, 2007 I have a source with an 89 AX-15 with NP231 attached from an 89 Wrangler. fairly low milage just over 100k. I have the infamous BA-10 made by the people that are shooting at us in Iraq. I am begining to believe there is a dirty bomb inside it and I am convinced that they have had a well though out plan to blow us up since 87. If you have a BA-10 get rid of it today. Notify DHS to pick up. LOL ;) Anyway it's out of an 89 Wrangler with the 4.0 4x4. I'm an 88 MJ 4.0 4x4. Should be an easy swap without any mods. If you know of any mods please let me know. I'm curious if the early AX-15's in mid 1990 at the change, had 21 spline NP231 or have they always been 23 spline? I will be installing a new clutch, but I would like to convert to external slave. Help here too? Anyone done the swap from 21 to 23 spline in the NP231? GO UT TEXAS Link to comment Share on other sites More sharing options...
Oizarod115 Posted October 5, 2007 Share Posted October 5, 2007 the input gear swap is as simple as any other teardown on a t-case... if you can do a SYE you can do a new input gear. as far as i know they were all 23 spline and the 89 wrangler transmission will work. it'll have a different shifter though, so try and find a shifter for an AX from a XJ/MJ other notes.. i asked a while back about converting to external slave and i think the response was either not possible or not worth the amount of work. don't remember 100% though Link to comment Share on other sites More sharing options...
Eagle Posted October 6, 2007 Share Posted October 6, 2007 The Wrangler transfer case is "clocked" a couple of degrees more than the MJs. It should still clear the floor, but it may be a slight interference fit. Also, the transfer case shift linkages are totally different. You'll have to use the MJ linkage, unless you want to butcher the floor pan of the truck. One of the shift arms on the YJ linage goes up where the MJ arm goes down (or maybe it's the other way), so pay attention to how your linkage is set up before you start taking things apart, because you'll need to figure out how to put it back together.

Pete M Posted October 6, 2007 Share Posted October 6, 2007 It's not very far off, but it is. Top pic is a stock TJ, bottom is a stock MJ Put them together and you get something like this: (TJ t-case in my 88 MJ) Link to comment Share on other sites More sharing options...
Oizarod115 Posted October 6, 2007 Share Posted October 6, 2007 well i have an XJ t-case and a YJ tranny. so which is clocked? the case or the tranny? Link to comment Share on other sites More sharing options...
Pete M Posted October 6, 2007 Share Posted October 6, 2007 I believe it's the transmission that does it. If I saw a random drivetrain combo sitting on the floor with nothing next to it for comparison, I'm not sure I could tell you if it was one or the other by looking at the clocking. :dunno: Link to comment Share on other sites More sharing options...

offroader461 Posted October 6, 2007 Share Posted October 6, 2007 you can pull the rear portion of the tranny off where the t-case bolts up and swap it with a XJ rear trans part...thats what i was going to do b/c the YJ clocks the t-case at about 10* more upwards...

offroader461 Posted October 6, 2007 Share Posted October 6, 2007 its actually not that hard...we did it on a couple of my buddies XJ's...we bought the YJ trans b/c they were cheaper than the XJ's and we swapped out the tail section and it reclocked the t-case to the proper position...i planned on doing this but havent been able to locate a tranny for a decent price....oh well my trans is great so eh :cheers: Link to comment Share on other sites More sharing options...
Pete M Posted October 6, 2007 Share Posted October 6, 2007 I like the bit of extra ground clearance the YJ/TJ tranny gives. :D Link to comment Share on other sites More sharing options...
Eagle Posted October 6, 2007 Share Posted October 6, 2007 I have the infamous BA-10 made by the people that are shooting at us in Iraq. I don't appreciate your sense of humor. The BA 10/5 is a Peugeot tramission, made in France. Since when are the French shooting at us in Iraq? Why don't we stick to discussing Comanches on this forum and skip the gratuitous political insults -- especially if you don't even know what you're talking about.

James and Sugarfoot Posted October 6, 2007 Author Share Posted October 6, 2007 France contracted with Iraq to build these transmissions. Thus explains just one of the reasons France did not want to be involved with bombing Iraq. Similar to the US never wanting to bomb Mexico or Canada. Too many US owned/financed factories exist.

James and Sugarfoot Posted October 6, 2007 Author Share Posted October 6, 2007 Another way to look at it is: Peugeot is to France, as GM is to the USA. Not all GM products are made in the USA. IE, Mexico, Canada, China, Taiwan, Vietnam etc. It's all about global manufacturing. I have absolutely nothing against the French. Grandfathers last name was LaFon. 2nd generation son of an immigrant direct from France to New Orleans LA. 1890. Link to comment Share on other sites More sharing options...
