Topic: dead 2.5 swap need help!

[Bounty Hunter]

Look for a 231c, same transfer case as yours but bolts to a GM transmission.

I may have the front have a 231c around here somewhere, then you can use the internals and rear case half of your 231j.

I'm seriously thinking about a 4.3/4L60e/231c swap, there's two on the local boards for sale, $600 and $450 complete with harness and CPU.  May just get them and store them until needed.

Where is this local board??? i'm needing one right now!!! and this is what i'm looking for except the 4L60E.

if you could find the 5 speed and np231c that comes behind the 4.3l i would use that.. my dd is a 94 s10 4.3 with the 5 speed and the tranys never let me down in 163K miles.

Well, you could run an SM465. They were in GM trucks and Suburbans up until '91 and have a 6.55 1st gear if I remember correctly. Granted, you'll have to use an adapter to fit it to the T-case, but the 465s are very strong and have a main case length of just over 12". If you want more info on them, there are a couple pages on the Novak site.

Then your asking the wrong question you need to find out whats available and then go from there. and find out what would work best with what is around

Ok here this the list and the question.1995 Yj rio grand(gonna end up with 4"lift and 33s), 1997 4.3L gm vin code W (engine,harness,ecm turns out my setup came out of his dads c1500 and not his extreme)sm465 trans,stock transfer case,and stock axles(for now).has anyone done this swap?If so please help me out,Novak adapter(motor mounts,trans to tranfercase) or advanced? Also how far forward(or back) did ya mount the motor(also did ya go to the pass side with it or dead center)?got all the parts tracked down just a little lost with where exactly to put the thing.the tub and front end are setting in the garage next to it as well(just ryno lined and looks to be alot easier to work on in this state).also would it be easier to use the stock manifolds or get a set of headers(for clearance)?
