Cant shift out of 2h, knowledge requested

It's about time you got on your knees to look from the driver side. It might be quite obvious by visual inspection. Another thing you can try is to disconnect the linkage and manually shift the tcase by hand. That will tell you if the problem is linkage, or tcase has a problem....

My 90 yj had a retainer clip issue that would allow the shift lever to be pulled up off of it and the pinch bolt in the linkage was an issue...there were a few times i needed to get under it and manually shift it at the tcase before i fixed it....interestingly it was also a np231
This is what ive been trying to acquire knowledge about...what potential problem may cause it to be stuck?

If you can't shift it by hand under the truck, then its time to take it apart and see whats going on.
As per the FSM
TRANSFER CASE DIFFICULT TO SHIFT OR WILL NOT SHIFT INTO DESIRED RANGE
(1) Vehicle speed too great to permit shifting.
(2) If vehicle was operated for extended period in 4H
mode on dry paved surface, driveline torque load
may cause difficulty.
(3) Transfer case external shift linkage binding.
(4) Insufficient or incorrect lubricant.
(5) Internal components binding, worn or damaged.
(1) Stop vehicle and shift into desired range. Or
reduce speed to 3-4 km/h (2-3 mph) before
attempting to shift.
(2) Stop vehicle, shift transmission to Neutral, shift
transfer case to 2H mode and operate vehicle in
2H on dry paved surfaces.
(3) Lubricate, repair or replace linkage bushings or
tighten loose components as necessary.
(4) Drain and refill to edge of fill hole with
DEXRON II® or MOPAR-MERCON® Automatic
Transmission Fluid.
(5) Disassemble unit and replace worn or damaged
components as necessary.

By the way merc225hp I've been following the Tcase busted thread, awaiting your solution..hope you get another one to fiddle with.
I also read somewhere on here about clunking while med. to hard braking, i believe it was in that thread actually, about early detection, wondering if this could be related,
I did notice today a clunk under med. braking and it triggered my memory of its mention.
