First verify if it is a shift position problem or an indicator problem. If the position is wrong, there is a shift linkage from the gear shift to the transmission that can be adjusted. If it is the indicator, then it is in the gear shift mechanism proper. I don't think it is possible for the transmission to change the angular position of the control shaft that engages various gears, etc. But the linkage could change.
While troubleshooting this problem, try to figure out why it happened. Is something loose? Did something bend the linkage while you were out 4-wheeling? Is something else about to break? Are your motor mounts OK, or has the physical position of your engine relative to the gear shift mechanism changed for any reason? I never had a vehicle do this, but maybe you are just lucky.

Can you or can you not take it out of park ?
Shift Lever Does Not Move with Brake Pedal Depressed
yes or no ?
PRND321 Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the gear position. The PRND321 display blanks if:
?€¢
The ECM detects a malfunction in the transmission range switch circuit.
?€¢
The IPC detects a loss of serial data communications with the ECM.
You have a transmission range sensor or PCM problem , Need a professional grade scan tool to diagnose the problem , well that would be the easiest way to test .You should have all modules test for DTC'S - diagnostic trouble codes ! That would point you in the right direction ! I would suggest you google class 2 serial data communication network !
From N to 4H
Stop the vehicle completely, place the
transmission in "N" (Neutral) and depress
the brake pedal and the clutch pedal fully
(if equipped), then push in and turn the
switch to shift into "4H".
From 4H to 4H LOCK
You can operate the transfer switch either
when the vehicle is stopped or while the
vehicle is moving.
Position the front wheels straight ahead
and turn the switch to shift into "4H LOCK".
If the vehicle is moving, we recommend
that the speed be less than 100 km/h (60
mph) during this operation.
NOTE:
• When shifting between the transfer
switch position and the transfer gear
position is unmatched, all 4WD indicators
will blink and the buzzer will sound.
• If it is difficult to shift between "4H" and
"4H LOCK" while the vehicle is moving,
try accelerating and decelerating your
vehicle several times after turning the
transfer switch. Be sure to wait until traffic
conditions allow you to accelerate and
decelerate safety before using this procedure.
From 4H LOCK to 4L LOCK
Stop the vehicle completely, place the
transmission in "N" (Neutral) and depress
the brake pedal and the clutch pedal fully
(if equipped), then push in and turn the
switch to shift into "4L LOCK".
From 4L LOCK to 4H LOCK
Stop the vehicle completely, place the
transmission in "N" (Neutral) and depress
the brake pedal and the clutch pedal fully
(if equipped), then push in and turn the
switch to shift into "4H LOCK".
From 4H LOCK to 4H
You can operate the transfer switch either
when the vehicle is stopped or while the
vehicle is moving.
Position the front wheels straight ahead
and turn the switch to shift into "4H". If the
vehicle is moving, we recommend that the
speed be less than 100 km/h (60 mph) during
this operation.
NOTE:
• When shifting between the transfer
switch position and the transfer gear
position is unmatched, all 4WD indicators
will blink and the buzzer will sound.
• If it is difficult to shift between "4H" and
"4H LOCK" while the vehicle is moving,
try accelerating and decelerating your
vehicle several times after turning the
transfer switch. Be sure to wait until traffic
conditions allow you to accelerate and
decelerate safety before using this procedure.
From 4H to N
64J209
Stop the vehicle completely, place the
transmission in "N" (Neutral) and depress
the brake pedal and the clutch pedal fully
(if equipped), then push in and turn the
switch to the mark (1) at the left of the "N"
position, and hold the switch in this posi-
tion for 5 seconds until the "N" indicator
blinks, then turn the switch to the "N" position.
When you turn the transfer switch to the
"N" position, "N" indicator will come on with
the buzzer sound.
CAUTION
• Be sure to stop the vehicle completely
before operating the transfer
switch to shift between "N" and
"4H", or between "4H LOCK" and
"4L LOCK".
• Do not shift between "4H" and "4H
LOCK" unless the front wheels are
in the straight-ahead position and
we recommend that the vehicle
speed be less than 100 km/h (60
mph).
Do not operate the transfer switch
while tires are racing.
• Do not operate your vehicle in "4H
LOCK" or "4L LOCK" on dry, hard
surfaces.
(Continued)
CAUTION
(Continued)
• Do not operate the vehicle while a
4WD mode indicator is blinking
except when shifting between "4H"
and "4L LOCK".
If you operate the vehicle while a
4WD mode indicator is blinking, a
buzzer will sound and the transfer
will shift to "N" (Neutral) to prevent
transfer case damage.
In this case, use the following procedure.
1) Depress the clutch pedal fully (if
equipped) or shift the automatic
transmission gearshift lever to the
"N" position.
2) Turn the transfer switch to the
position previously selected.
3) Operate the transfer switch again.
