I got a transfer case from Twisted at the last club run. He said it might be a 231, but he was unsure. How can I tell what kind of transfer case I have. It has no tag on it, but it does have some numbers that are molded into the cast.
I search online and I couldn't find anything about it. Any help would be good, and I can get pics if needed.
Thanks.

if it is a np 231, there will be a round tag to the left of the rear output shaft, it will say new process 231 bla bla bla..

There is not tag, I think it fell off. I know its made by NP because it has NP stamped on to the cast.

yes, there is no tag. i dont know where it is. it came in the back of my MJ. i assume its a 231 becuase my MJ has a 231. is there a way to pop open the internals and see if it has the full time differential in there?

count the clicks in the shifter.....or look at it and look under your MJ and itll be pretty obvious because the FT case is noticably different

There is no shifter connected to it, could I do the same with a wrench. The transfer case was in the back of his MJ, not in it. It is now in my basement.
I want to know if there was some other way to identify the transfer case before I start to take it apart.

I hope not. I have an NP249 in my Jeep and this is the one I am replacing it with (along with a rebuild and a SYE). But my 249 has a tag on it.

it appears that what kaiser said is a sure-fire way to check which one it is. look in the link that posted above, and 5-90 gave a good answer. good luck casey. if it is a 242, i can take it back if you want. i kind of want a 242 in my jeep.
