Just curious. The User's Manual for my '07 C6 w/ auto trans says that
to shift out of Park when the engine isn't or won't run, pull on the
shift lever slightly and just hit the Accesory button twice to pulse
the tranny selector engagement switch. But what if there is no battery
or a dead battery and you need to move the car to get access to under
the hood? Some other models have a small detent somewhere that allow a
screwdriver to be used to disengage Park.
