NP241 or NP231 OR ???

Okay guys, so I rebuilt my TC over the weekend and installed an SYE kit and then my brother in law hit the gas and not the brake pulling in my garage and knocked the case off my work bench and the case is now destroyed. I have a budget of 1500, for a new case and am thinking about either an NP241 from a 2003-2006 TJ, or a JB Conversions HD 231, or maybe something else. Anyone have any constructive input?

If you can swing it the 241OR would be a nice setup because you get 4:1. Otherwise the JB is a nice setup, wide chain, 6 gear planetary.

Does anyone have the link for the magazine article showing the 241 being installed in an XJ?

the ruby 241 is a big upgrade , but big dollars & sometimes hard to find. mine cost me $1800 , and i got a good deal, all the others i found were 2 k & up. jb does make high quality items.

Was it a difficult swap or bolt in?

its a bolt in, but there are some issues to deal with . like shifter hookup, speedo cable, rear driveshaft replaced. nothing too hateful, just some time & more money, yet its still worth the effort. the low range is super low.

My 241 was a drop-in with only the VSS being a issue! I bought mine brand new when they first came out. It's been 15yrs but I think I had to flip the shift linkage around.

So if you all don’t mind my asking, which 241 do I need? NP241J, or the other one?

If you want the 4:1, you need a 241OR RockTrac from a TJ/LJ Rubicon.

Re: NP241 or NP231 OR ???

I swapped a 241J from a TJ a few weeks ago. I ended up clocking the case to get it to fit with my existing skid plate/ cross member and had to notch the exhaust bracket under the transmission mount.



I used yokes from Power Train Industries to save a few bucks over JB. They have the correct counter bore for this application and the dust shields/
