I'd inspect things like u-joints, greasing the driveshaft slipjoint at the xfer case, etc prior to suspecting the trans or t/c.

After taking a break from this issue, and messing around with some other thing, I came across some info about adjusting the tv cable manually. I've adjusted it with the self adjuster a half dozen times, but decided to adjust in manually and make it a little tighter.

My first adjustment was to push the plunger in a MM or 2, and take it for a quick test drive. I immediately noticed it was shifting better, but was still getting the TC problem of it locking and unlocking while coasting downhill.

So, adjusted it another MM shorter (Pushing the plunger in) and took it for another drive. Shifted even smoother than the last time, and had no jumping from the TC locking and unlocking while coasting.

That was two days ago. Today, I had my normal 20 mile drive to work, lots of hills I end up coasting down, and where as I wouldn't call it 100% perfect, I'm satisfied with the 95%. No more jumping between lock and unlock, but there is still a slight hesitation when it wants to unlock. All in all, It drives like a completely different jeep.

The only thing I can think, is the TV cable is stretched and needs to be adjusted tighter than normal. With the end of it unhooked, its my understanding that the plastic clip should be just about centered with the post, when all the slack is pulled out of the cable. Mine now a good quarter to half an inch shorter, but it is difficult to tell the exact point where all the slack is out of the cable. Either way, it appears that the self adjustment on my cable isn't adjusting it correctly.

Stretched cable? Something messed up in the tranny? Its beyond me. So, wish I could explain why this solution is working for me, but I don't have the knowledge. All I can say is it worked. Thanks everyone for all the help and suggestions along the way.

Now... on to the next issue.
this worked for you?? I have the same problem right now. And it’s driving me up a wall. I just can’t seem to get it figured out. You’re saying that you made your kick down cable tighter??
