How do you unlock a GMC Hummer automatic transmission from the park position once the vehicle looses electrical power.

If you remove the shift handle, and lift the cupholder/indicator assembly out, there is a push button release on the solenoid. It looks like a large rivet head, approximately the size of a niickel.
