Yo,
To shift to N (neutral) from either 4H or 4L;
To shift into N (neutral), stop the vehicle and engage the parking brake. Place the automatic transmission into NEUTRAL or depress the clutch on manual transmission vehicles. From either the 4H or 4L position, push the transfer case shift **** down (toward the ground) and at the same time move the transfer case shift lever to the N (neutral) position. The N (neutral) position should only be used for vehicle towing.
NOTE: Dash mounted four wheel drive indicator lights are off when your
vehicle is in neutral.
To shift from N (Neutral) to either 4H or 4L, stop the vehicle and engage the parking brake. Place the automatic transmission into N (Neutral) or depress the clutch on manual
transmission vehicles. Push the transfer case shift lever to the desired position.
*** If it is difficult to shift into either 4H or 4L, it may be necessary to let the vehicle roll slightly and/or turn off the engine (particularly on vehicles equipped with
automatic transmissions).***

1356 Electric Shift Emergency Shifting; "... I recall in same thread Ricky B wrote this, "I'd thought I'd share some pics for those who may like to know what the t-case 12 volt shift motor does. Or is supposed to do in my case. Just for drill I removed the small motor. You'll only need a 3/8" ratchet wrench and a long 10 mm socket to remove all 6 bolts. Three of them are about 1 1/2" long and goe thru the top right circular head of the motor. The other three bolts are about 3/4" long. One bolts to the bottom flat tang of the motor case itself (ground?) and the other two hold the wire coupler harness in place on the t-case. As I suspected the triangular shaft inside of the t-case was pointing down to indicate 4 High. By merely jiggling the front drive shaft yoke a little bit with one hand, I could very easily move the triangular shaft with my other hand and get it into 2 High..." by Justshootme84 (RIP FRIEND), Broncobill78 (Dave), &
