Transfer Case addition

[Fire4755]

I need some help. I just bought a np231 out of a '98 xj. i am converting my 4.0L 5 speed '88 Comanche to 4x4 and want to know what all i need to make this t case work with my tranny or whats the easiest cheapest way to get it in my truck. also it did not come with the linkages or anything else just t case so if anyone has pics of what all i will need to find or make please help me.

Thanks

Jamie :help: :dunno:

if it makes a difference i am custom making a rear drive shaft

Also the xj it came out of was a five speed manual. thanks

the trans is a ba10/5 if it's original, and so your t-case won't work. it's a 21 spline.

 

the planetary assembly has different cuts in the '88 tcase, so you can't even swap the input shaft.

i thought i had the ax 15 tranny

[JeepcoMJ]

if it's an '88, it has the peugot ba10/5

 

...unless someone swapped in an ax15.

i was really hoping i wouldnt have to i only have 65000 on my whole truck so i was trying to use as many of my parts as possible:(

regardless of which transmission, if your truck is currently 2wd then neither one will work anyways, you can't feasibly convert a 2wd transmission to 4wd, you need the 4wd manual transmission

it says it's a 4x4, and you're wrong. it's very feasible to convert a 2x4 trans to 4x4...you just need the proper parts from a bad transmission.

so ether way i would have to get an ax 15? anyone know a good place to get one cheap and how much it would run me?

[Fire4755]

and would it be a direct replacement or would i have to do anything?

[Fire4755]

or should i just use this? its a 87 JEEP WRANGLER ba 10/5 and t case would it work in my truck?

that's overpriced on the trans by about $249, and transfercase by about $100

 

an ax15 would be about $150-$400 depending on your area and miles, and it's more or less a bolt-in.

So all I need to get to swap trannys is just the tranny itself and then I'm guessing I need slaves as well? Would the clutch I has still work or no? And would I need any adapters off the engine or is it a perfect fit?

I believe the crossmember/trans mount has to be changed also google "AX-15 swap" you'll find a ton of info on it.

is a wrengler ax15 the same as a cherokee one or are they different sizes and adapters and all?

The tranny's the same except it has a different mounting for the tc. It rotates it up more towards the body so you may have to do some "clearancing" to get it in if you go that route.
