hello how is it going, some of you may have seen my post about picking up 2 87 cherokees, one is a wagoneer with the 4.0 & a 5 speed along with an np231 and thew other is a 2.5 with a 5 speed and np207, my buddy took the wagoneer so I am stuck with the 2.5, plus side is he said I could have his np231 and even tranny if I wanted, i was thinking I would keep my tranny and just throw the np231 in, that is where my question arises, will it be a direct swap as far as linkage and mounting goes? I know I may need to pick up a yoke that matches the np231 but other than that will I run into any problems?? Thanks, have poured over the stock spec list as well as been searching, couldnt quiet answer my question though. thanks!

 

bump** This is tomorrows project, any insight would be greatly appreciated, if not ill let you guys know how it goes.

 

I've done this swap in my old '86 cherokee pioneer with the ax5 manual Trans.. You will most likely need to open up the transfer case and switch out the input gear. You can go to novakconversions.com for the input gears and find which one you need. You'll also need a different length linkage bar. I took mine to the local machine shop to have it lengthened or shortened, can't remember. Good luck, the np231 is a much better TC IMO.

 

Can any one confirm this? As far as I can tell if the jeep the transfer case came on had a manual tranny and was pre 90s it would be a straight bolt on to another pre 90s manual xj, seems logical to me, only side by side difference is the 231 has a shifter linkage that is about 2inches longer..
