NP241OR swap problem

[nightkrawler]

sorry about that. 1996 cherokee aw4. i swaped out the 231 for the rubi 241or the problem is w/the aw4 tranny the rear speed senor is imprtant for trans shifting, the sensor on the rubi tranfer case is a hall effects design, is smaller than the one from the 231 and of course the connectors are different. i guess what i really want to know is can i just splice in the rubi sensor to the aw4 harness and will it work, or is there something else i need to do? thanks for your help.

You will need the male connector from any newer Jeep that runs that style VSS. I got mine off a TJ in a wrecking yard. Splice in the three wires and it works. Wire colors probably wont match exactly. Center wire on both harnesses is the ground. My 95 XJ has a Orange and White power wire and that was the same color on the Plug that I was splicing in.

I did the same swap on my '94. Just as rockslut said, once you connect the 3 wires you're good to go. The only problem I had was speedo calibration. Had to buy Superlifts speedo calibration unit ($175). Mine was off by 17%. You can probably get by if it's only a few % off. Can't fool that ole computer.

oh i know i'm ganna have a problem with calibration. i'll be running 38" boggers. as far as speedo being correct.......i can live with it for a while. will it affect transmission shifting?

About six months ago you could find them for $1600+. I looked today and JB Conversions are now selling them for $2150. I guess there is some demand for them now. http://www.jbconversions.com/pages/products/nvg241OR/index.html

Probably worth giving Josh Cumby a call at High Impact, he may be able to come up with a better deal. http://www.high-impact.net/transmission_and_gear/transfer_cases.htm#NP241OR%20-%20%22Rubicon%22%20Tcase

Ouch!!!!! That hurts... I was hoping around the 1000$ Range. Oh well Ill add that to my wish book.

 

[redneck23ms]

you can sometimes find them used in the $1000 range. for 2100 you can get an atlas slightly used

I bought mine on e-bay for $900. I saw another there recently for $750. Rubicon axles and t-cases show up on e-bay quite often.
