Truck cant shift out of 4 weel drive or neutral

[Mad35]

So here it is, I was driving my lovely and newly 6' lift 88 ranger with 2.9 liter engine when all of a sudden I lost all power to the wheels, almost like its stuck in neutral, then I tried switching the 4WD low function to 4WD high or 2WD high or even neutral I found it won't budge, any input would be well appreciated, I'm thinking i piled up the transfer case, but as its stuck on the river I have a chance to trouble shoot it before we pick it up later tonight, rather not fix it in frezzing cold snow as I live in Canada, thanks in advance!
