The only way to move the vehicle other than dragging the rear tires is to lift the rear wheels with a "capture-type" tow rig and then to tow onto the flatbed with the car resting on the fronts. Most tow operators will just slowly slide the tires or will place dollies under the rear wheels.

What is transfer case clutch? If battery is dead ( or goes dead while car is parked?) the transmission P is in fact same as N? The transmission is not locked when in P if battery dies? Ie. if you park on a steep hill without parking brakes, your car will slide down if battery dies? Oops...
Or is it so that front wheels can roll freely "in battery dead mode" even if gear is on Park. And that will not cause center differential to explode...?
I remember that if a big truck must be towed, you have to detach driveshaft from rear end in order to keep transmission in good shape.
A nice picture would do a lot of explaining... what all rolls free if gear is on P and battery dies?
