Supposedly these new encoder motors are shipping in the neutral position.
How can you get the transfer case into neutral manually, or b) get the new encoder motor into the neutral position manually.
One opinion that says you should be able to hook up the electrial wire to the encoder motor before installing it and put it in neutral through the dashboard switch, then install it.
Option b is not possible.So try this procedure:----
Removal Procedure
1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the transfer case shield. Refer to Transfer Case Shield Replacement .
3. Remove the front propeller shaft. Refer to Propeller Shaft Replacement - Front in Propeller Shaft.
4. Remove the motor/encoder electrical connectors.
5. Remove the motor/encoder mounting bolts.
6. Remove the motor/encoder assembly.
7. Remove the motor/encoder gasket.
Installation Procedure
Important
o If the motor/encoder assembly is being replaced because it is defective, make sure that the transfer case is in the neutral position. Manually shift the unit at the shift shaft. Use a crescent wrench if necessary.
o When installing the motor/encoder unit to the transfer case, make sure that the transfer case is indexed properly and it is flat against the transfer case before tightening the mounting bolts.
1. Install the NEW motor/encoder gasket to the transfer case.
2. Install the motor/encoder to the transfer case.
Notice.
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
3. Install motor/encoder mounting bolts. Tighten
Tighten the bolts, in the sequence shown above, to 20 N·m (15 lb ft).
4. Install the motor/encoder electrical connector. Ensure that the retention clips activate.
5. Install the front propeller shaft. Refer to Propeller Shaft Replacement - Front in Propeller Shaft.
6. Install the transfer case shield. Refer to Transfer Case Shield Replacement .
7. Lower the vehicle.
1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

-------------------
Start the engine. If that's not an option then turn the key to the RUN position. Make sure the t-case is in 2HI and the switch light for 2HI is on and steady.
Press and hold both the 2HI and 4LO buttons for at least 10 secs. The NEUTRAL light should come on. Put the tranny lever in REV for one second and then in DRIVE for one second.
Press and hold both the 2HI and 4LO buttons for at least 10 secs. The NEUTRAL light should come on. Put the tranny lever in REV for one second and then in DRIVE for one second.
This transfer case also has a NEUTRAL position. A shift to the NEUTRAL position allows the vehicle to be towed without rotating the transmission output shaft. NEUTRAL position may be obtained only if the following criteria has been met:
| • | The engine is running. |
| • | The automatic transmission is in NEUTRAL. |
| • | The vehicle speed is below 5 km/h (3 mph). |
| • | The transfer case is in 2HI mode. |
Once these conditions have been met, press and hold both the 2HI and 4LO buttons for 10 seconds. When the system completes the shift to NEUTRAL, the red Neutral lamp will illuminate.
NEUTRAL: To Shift the vehicle's transfer case to NEUTRAL while towing your vehicle.Shifting into NEUTRAL
To shift the transfer case to NEUTRAL, first make sure the vehicle is parked so that it will not roll:
1. Set the parking brake.
2. Start the vehicle or turn the ignition to RUN.
3. Connect the vehicle to the towing vehicle.
4. Put the transmission in NEUTRAL (N).
5. Shift the transfer case to 2HI.
6. Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.
7. Shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second.
8. Turn the ignition to OFF
9. Place the transmission shift lever in PARK (P).
10. Release the parking brake prior to towing.
