transmission swap and 4x4 upgrade

[trackstar8652]

I have an 87 Comanche with the BA/10 and is 2wd. The transmission is on it's last leg at 246k. I want to swap out for an ax-15 or NV3550. I have never swapped a transmission before and am confident I can figure it out, but what am I getting into as far as a 4x4 transmission with a NP231 transfer case attached. What tech pages could I be linked to? Any tips? What transmission will fit and what if any modifications need to be done? The more info the better!!! Thanks guys in advance! :wrench:

thanks for the link! Now does that apply to the NV3550 as well? If it is from a TJ will the bell housing be the same for the old 87 4.0?

yes, the wrangler bellhousing will bolt to the older 4.0s :thumbsup:

 

keep in mind that the wrangler trans will rotate the t-case up a bit higher than a stock MJ. puts it real close to the floorboards, but it should be fine (and give better ground clearance). several guys have used the wrangler trans. you'll want to grab a shifter from an MJ/XJ though, as the wrangler one is different and doesn't fit well in the MJ cab. also you'll need MJ/XJ t-case shifter brackets/linkages.
