Issue: Placing 6spd. auto-trans vehicle in PARK does not hold the vehicle in park whether it is running or not. Vehicle in question only has about 10k miles on her. Possible solutions: Is this a transmission issue, an isolated shifter issue, some type of pawl plate problem/linkage, etc.? It is a warranty vehicle, fwiw. I realize it could be a multi-faceted issue and the vehicle is of Ford manufacture, fwiw. Thanks for any help.
