Question about 2006 GMC Envoy Denali
Hi Charles, Take the vehicle for a diagnostic scan. I think the problem may be connected to a speed sensor (found on each of the wheels) If one fails, incorrect signals are sent to the ECU and the box will fail to change gears. Regards John

Rear fuse box is under the seat bottom, rear seat (middle row) on the driver's side. There is a plastic cover over the top of it that snaps into place.

yes you must have a leak somewhere. maybe in the air bags or the lines. jack up the car while there is still air in the bags get some soapy water in a spray bottle and start spraying the air bag and lines and pump until you find the leak. then replace whats needed.
