NP229 To NP208 Swap

I have this NP208 out of a Jeep lined up for me on Craigslist for $60. Looks good in pics and guy said it ran great when pulled. I'm going to scoop it up regardless but wanted to see how hard of a swap it would be. I plan on swapping it out once (if ever) my 229 craps out from abuse. Would the vacuum and electrical just plug in? Here's a pic from the ad.Thanks.

You'll need longer driveshafts check the spline input on it make sure it matches the 229

Cool, thanks. Good to know about the driveshafts, I was planning on upgraded to some heavy duty custom made d-shafts but now I'll wait for the swap. What is the spline count on the 229? Thanks again.

I don't remember 23 I think but as long as the 208 came out of an fsj and not any other make it should be the same as a 229

There was a rare higher spline version in the J-20 as I recall, but 99% of them are the stock 23 spline. They are bolt in, but you should get the shifter flag & linkage if you can as the flag notations are not the same as the 229. if it were me, I'd also rebuild the 208 while it's on the bench. It's easy and takes about 2 hours from start to finish.

Front drive shaft will be the same, rear needs to be longer. Your 229 shifter and linkage will work, but like Ryan said the flag's notations are different.

You'll need a d-shaft from a QuadraTrac rig for the rear...I've got a 208 shifter handle if you need it.

Thanks guys, lots of good info. The guy said it came off a J-series truck and fits 80-87 trucks,Cherokee 80-83 and Waggys with auto trans. I was planning on rebuilding it once I picked it up and had some free time. Are any of the internals the same as the Chevy 208? I have a few Chevy 208's lying around from my K5's I've had (before I did the 205 swap). I guess I'll find out. I'll keep in touch bowtieman55 about that shifter. Thanks. We'll see if the 229 ever craps out since I just did a good overhaul on it when I got it(cracked case inspected internals and replaced seals). The fluid in it was greyish red! I filled it back up with 2qts Royal Purple max ATF and 1qt Lucas tranny additive. Working great so I guess I'll see once spring time rolls around and hit the Rubicon.

internals are the same (I think the input & output are different) but the cases don't have the same bolt pattern
