I apologize for what might be a really strange post. Any help or suggestions would be appreciated. I am continuing my restoration project on my 1986 Commanche 2.5l gas pickup. Four wheel drive. I know it is 4 wheel - from underneath - but: I am in the process of starting on the interior, and I was looking at the high-low lever and the shift lever. What has become rather obvious is that there is no "select-trac" lever on the plastic surrounding the stick shift. Nor is there any place for one. So either the surround is not original, or it is not a ":selec-trac" transfer.. Further investigation shows that the transfer case is a New Process Gear 207AM3. So here are my (admittedly odd) questions: 1) What kind of control did (does) this transfer case have? Is it a mechanical lever, an electrical switch, a vacuum switch, or what? 2)Is this the right transfer for an 86? 3)What parts am I missing? My previous experience is only with military 4wd vehicles. This jeep is the youngest vehicle I have ever worked on, and I admit I am out of my depth. Levers I can figure out....

Hello everyone! I joined the Comanche Club last week when I purchased an '88 Comanche. She's a beauty. But I'm having an issue that I can't explain. When it's in 2wd, it goes great. But when I put it in 4wd, the rear driver side wheel seems to move slower than the rest, and just skids along. It almost looks like it is trying to go backwards. Everything that I can think of that would explain it, would also manifest in 2wd. So I'm super confused. Any thoughts?

Hi everyone. First time poster here. I bought my Comanche a few months ago from a guy who bought it with the intention of fixing everything up, but then I guess lost interest/lacked knowledge, and wound up unloading it for cheap. I've been working through many of the problems he avoided (and some of the ones he fixed... ...) but one so far has left me baffled. The thing is stuck in 4 wheel drive! It has the NP231 (Command Trac) and when I start the vehicle it shows 4WD on the dash, plus, when I drive it around the block I can definitely feel crow-hop going on. With the t-case selector in 2wd it's in 4wd. With the selector in 4wd high, it's in 4wd. I think it switches to 4 low with the selector, but haven't really checked that. Regardless, the case won't switch into 2wd. In order to get the truck home from where I bought it I tried everything I could to get it into 2wd. I went in reverse and backed up, I tried turning while in reverse, doing 30 I dumped the trans into neutral, played with the t-case lever, and then back into drive, I got under the truck and manually moved the adjuster, I banged on the adjuster with a rubber mallet to make sure it was making full travel (I think it was)...I've still got nothing. In order to get the truck home from where I bought it I wound up pulling the vacuum coupler off the CAD which turned off the dash 4WD light and eliminated crow-hop (it was definitely in 2WD) and then I drove it 150 miles home. When I got home I tried connecting the CAD vacuum once again to see if it shook free of 4WD and even after all that it still hadn't. I took the CAD fork assembly off and pulled vacuum on each of the ports to see if it were hanging up somewhere and it moves freely in both directions. I think part of the problem is I don't fully understand what happens when I pull the t-case lever. Obviously the front drive shaft becomes engaged, but what activates the CAD? What switches the vacuum from one side of the CAD diaphragm to the other? Where is that valve/switch/doo-hickey located? Where does the 4WD dash light signal come from? I obviously interrupted it by removing the vacuum coupling from the CAD, but the mechanicals in the t-case are still in 4WD orientation right? Can someone supply a play-by-play of whats supposed to happen when I throw that t-case lever into 4-hi? Or at least a list of things I may want to check. Anyway, this general lack of 4WD understanding is keeping me from driving my Comanche! So...any help is much appreciated. Thanks guys!
