To those reading:
If you have to tow a GMC with front wheels on the ground, if you can run the engine it will be a much better experience.
The transmission pump is driven by the shell of the torque converter, so as the engine is running, it will be happy.
With the engine running, you will also have the power for steering and vacuum for brakes.
If you have ever wondered, I strongly suggest that you do this experiment. Find a huge empty parking lot or the like. Be very aware of what
obstructions you might encounter. Get your coach rolling and shut the engine down.
Now, try to steer it. This will take a serious effort. It may cause it to spill some fluid, so have make up handy. If you don't have really good
shoulders, you won't do much....
Same Game, but now with the engine shut down, try the brakes a couple of times. After the second, you will have to bend the steering wheel to do any
good at all. This is why many of us have electric backups for the brakes.
As a side and sort of unrelated note. If you loose a drive axle joint, any part of the final drive or the shift cable is compromised, you also may
have no park effect at all. Carrying a chock is a good idea.
