I see the stories of stuck parking pawls still go on decade after decade after decade.
The pushbuttons really have nothing to do directly with this issue, but they are often blamed.
And I still see people struggling with selector-lever Ultramatics too...1955-56. Locked in Park. I've seen selector levers bent around in the shape of a "J" by someone trying to King-Kong the durned thing into submission. HINT:if your selector lever seems locked in Park, it is a very simple matter to reach under the vehicle and push upward on the linkage... which usually pops it right out of what seems to be a locked-up condition.
Packard issued remedial fixes for stuck V8 parking pawls... for both the selector lever shifter and the pushbutton gear selector. These were clearly listed in Service Bulletins.
And regarding pushbuttons-especially when the mechanisms are old, worn and tired- the smartest thing to do is NOT to shift directly out of Park into Drive... but rather get into the habit of punching (from Park) to Neutral... then Drive. The possibility of over-travel and bent contact fingers is hugely reduced. In all the years I used pushbutton Ultramatics... I never had one lock up or over-travel. But I always used this method. And I always did the factory retro-fits on my Ultramatics and linkages.
