Auto.gear shift lever suddenly very hard to move into Park.

No, definitely not. I drove about 20 miles & the button wouldn't push in to connect in order to Park. Left it in neutral,keys in ignition with emerg. brake on. However, after returning home, the button depressed & able to move it into Park. Haven't driven it since.

Try spraying some WD-40, straw attached to sprayer, around the release button. Wash it out well, while pushing it in and letting it pop back out. May be gummed up inside from soda,coffee and the cooler weather we have now is making it worse. (Maybe) I don't think First Team Subaru will give out any info. on another problem with this if you called them, just tell you to make an appointment. Franklin County Va.
