NV249 and NP249

Are these two TC's exactly interchangable?

So are you saying they swap out if they are the same year?

yep
but i doubt you would find a nv and an np in the same year
earler modles are new process then the name switch 94-96 i think to new venture gear
but for your year you could use anything from 96 up for sure 6 or 8 cyl for the 249.

I crawled under my jeep and the round metal tag on the TC definitely says NP 249 J. I bought it with 100K 5 years ago and have put on 45K. Perhaps the previous owner changed the TC once already from a NV249. Have found a replacement NP249 but from a 96zj. The photos I've seen look a little different from mine. The housing around the VC is what looks different. I think I will have to find a donor from a 98zj to be a match. I work on teeth all day not cars so this is a huge learning curve for me.

if you go for a 98 you will be fine as I said they are both the same company. they did change name but who knows how many 249 were already built.

I just firgured it would be more cost effective to not have to mod for the 242. I'm not sure how much longer I'm going to keep it. I think I might need more space for teenage boys and all their stuff.

i hear the teenage boys and all the stuff girls are fun too i had both.
dispite what you may read the 249 is a good tc.
just need to keep up with maint and keep a good eye on tires.
One or two pounds low on one can cause problems

Thanks for the advice and the link. The link showed me that there is another version of the 249, 249 OD. I'm not sure if that applies to me. How can I tell??

I know the earler versions did not have low range but I think the od is for another product ford chev or something.
od stands for On demand. i suspect like the 4x4 durango i rent last weekend it did not have any way of shifting the tc it on demand sent power to the front as required.
don't think you would have to worry about it if you stick to jeep but i guess it wouldn't have a shift linkage.
here is a better link for specs
