more than like have a broken axle shaft, un hook the rear drive shaft and put it in 4wd if it wont move then you know you got a broken axle shaft or spider gears broke in the pumpkin

Do you have all 4 tires matched to each other? If you have 1 worn and 3 new, expect problems. Also, 2 tires on the front from 1 mfgr and 2 on the rear from a different mfgr will cause no 4WD. If all 4 tires match, put it in 4WD and tap on the transfer case and the front shift mechanism on the front axle. One or the other may be stuck, assuming that the 4WD fuse is good. The fuse is in the fusebox under the dash.

The transmission is controlled by the Transmission Control Unit (TCU).
Throttle
position, rpm, and speed are input parameters to the TCU. The TCU has a
default set of shift patterns. These shift patterns change over time
based on your specific vehicle setup and driving habbits.
The
shift patterns are only slightly affected by driving habbits over many
driving cycles. But, changing the relationship between the throttle
position and the actual speed being reported by the speed sensor can
have an immediate effect on shift patterns.
While your speedo
may now be correct, the realtionship between rpm and thottle position
has not been corrected. That would take a gear change in the
differentials.
The TCU can be reset to an inital learn base line. When this is done, the TCU will instantly learn the dynamics of your setup.
Any shop with an advanced ODB scan tool can reset the the TCU. The dealer or a transmission shop would be preferable.
You really should change your differential gears as opposed to resetting the TCU

there is a solenoid that releases the shifter when you step on the brake pedal.there is by the shifter a little tab that can be popped out with a small screwdriver,and using your key,put into the hole and the mechanical device will release the shifter.
it is called a shift lock override
