Only way for this to happen on an H2 (AWD) is for something to break rearward of the lockup hub. Take a look at the splines between the intermediate shaft and centerdifferential or even the teeth on the forward sun gear and/or stepped pinion on the center diff.
As long as you have the t-case torn down for repair be sure to upgrade to the new aluminum mode fork (production upgrade to old plastic forks thru end of 2007 or so). You should also upgrade the rear half of the housing to the 2008 version which has a pressed-in rear prop bushing (better bushing and is also replaceable.

SOURCE: shifter is stuck in park
The shift cable is off the lever on the trans...the dash indicator states drive but the shifter is in park. Look under the drivers side of the trans, next to the catalytic converter(make sure the truck is cooled off) the trans cable will not be attached to the tranny lever-re-attach and you will be able to get it home or to a shop for a repair. This happened to me already, simple fix.

Check the linkage that goes from the shift lever down to the transmission. It sounds like somewhere along the line, it has become disconnected or has broken.
if that parts are clean then It sounds like you have a shift control solenoid that has high resistance causing the hard shift you describe. Scan the PCM for trouble codes if none are present you could have a internal transmission problem.
