This vehicle had option of three different transfer case ! Which one of these is the one in your vehicle ?
Transfer Case - NVG 120-NR9 Transfer Case - NVG 126-NP4 Transfer Case - NVG 226-NP8
The New Venture Gear model NVG 226 RPO NP8 transfer case is a two speed automatic, active, transfer case. The NVG 226 provides five modes, Auto 4WD, 4 HI, 4 LO, 2 HI and Neutral. The Auto 4WD position allows the capability of an active transfer case, which provides the benefits of on-demand torque biasing wet clutch and easy vehicle tuning through software calibrations. The software calibrations allow more features such as flexible adapt ready position and clutch preload torque levels. The technology allows for vehicle speed dependent clutch torque levels to enhance the performance of the system. For example, the system is calibrated to provide 0-5 lb ft of clutch torque during low speed, low engine torque operation, and predetermined higher torque for 32 km/h (20 mph) and greater. This prevents crow-hop and binding at low speeds and provides higher torque biases at higher vehicle speeds, to enhance stability.
The New Venture Gear model NVG 126 RPO NP4 transfer case is a one speed automatic, active, transfer case. The NVG 126 provides only one mode, Auto 4WD, and is transparent to the operator. The active transfer case provides the benefits of on-demand torque biasing, wet clutch and easy vehicle tuning through software calibrations. The software calibrations allow more features, such as flexible adapt ready position and clutch pre-load torque levels. The technology allows for vehicle speed dependent clutch torque levels to enhance the performance of the system. For example, the system is calibrated to provide 0-7 N?·m (0-62 lb in) of clutch torque during low speed, low engine torque operation, and predetermined higher torque for 32 km/h (20 mph) and greater. This prevents crow-hop and binding at low speeds, and provides higher torque biases at higher vehicle speeds, to enhance stability
The New Venture Gear (NVG) model NV120, RPO NR9 transfer case is a single speed, full-time, all wheel drive (AWD), transfer case that incorporates a front/rear drive differential carrier assembly.

Sounds like the shifter is stuck in reverse or drive since it will roll.
I would set the parking brake and have someone watch the shift lever on the transmission to see if it and the shifter inside is still connected.

Under the console, between the seats. Have the codes read first. These modules aren't cheap.

you need to hook up an obd2 scanner to the port under the steering wheel and see what your computer says which sensor or circuit is acting up

Try another repair shop. Someone must connect some measurment equipment to your car, to find what is wrong. That is the fastest and most best way to solve this.

I doubt very much it is the accelerator pedal which is basically just a potentiometer to feed go faster/go slower information to the brain. These things tend to either work or not and don't usually play hide-and-seek.

On those vehicles equipped with anti-lock brakes the same sensor information can be used for an electronic stability control system to improve traction in poor conditions by detecting which wheel has lost traction and applying the brake on that wheel. If the system cannot cope the engine power output will be cut until traction is restored.

It would seem the system has a fault and should be checked out by someone familiar with that type of magic.

The heater control module is bad, it is fairly easy to replace. Here is a link that explains it. Sparky Answers

CHECK THE ALTERNATOR OUTPUT AND BATTERY

2006 GMC Envoy... | Answered on Dec 18, 2014 | 22 views


Could be a bad connection to the battery; test by noting if the headlights are bright and stay bright while trying to turn over motor. If not, try tightening battery terminals and ground or get replacement terminals. Could be a bad connection at the solenoid (lump on side of starter motor); tighten connections there. Could be a bad solenoid or starter motor; check shop manual for repair.

The indicator for park/neutral is changing on the dash without you moving the shifter?
If so...the park/neutral switch on the transmission...(or could be on shifter housing) is informing the lock control module/body module... that the vehicle has been put in park...thus the door unlock actuation...then..apparently the switch is erroneously informing the lock module that it is in neutral...drive...thus locking the doors....could also be a fault in the general body module...which ..most likely...controls most of the body systems via CAN BUS....Controller Area Network system....
Odd that no codes are in the body/lock module....make sure your scan tool is indeed able to access the body control systems...if not...you need to find a location that will provide that service.

I certainly would!
The BG synthetic transmission oil is your best bet as a refill fluid.
Insure it is compatible before purchasing service or fluid if you are doing yourself.
A vehicle this heavy should have a trans service every 60K...if you are using synthetic...every 30K if not.
