So I have a 95 rio grade with the 2.5i and I'm wanting to start preparing a sm420 granny low transmission to swap out the ax5 has anyone else done this? What kind of results should I expect? Any ballpark estimates for rebuilding the sm420? If you know anything about this swap pass it on to me. I been reading up on it on Novak.

Thanks,

They say on Novak a ax15 won't work and I never get in 5th gear anyway but they say the bell housing off a 2.8 blazer will bolt the sm420 to the AMC 150

You can bolt an AX-15 to a 2.5L. You need to do some research, we bolted on up to his 2.5L using a dodge bell housing. Im not sure on the rest of the parts as I just helped him with the tranny install. BTW your NP231 will not bolt to an AX-15 so you would need a NP231 from an AX-15

Yeah that's what it was. But it said the sm420 would bolt right up to my transfer case. And also kinda like the low ratios in the 420

Well would it matter what the ax 15 came out off and what about the cross member? Would it need to be modified?

Actually I've got the wrong bellhousing for the 2.5l, the two I have are for a dodge 3.9l v6, realized it wasn't the right one for the swap a few days ago but since the op hasn't replied I didn't say anything. If I do come across one I'll pm you though
