Hello everyone. I have a 91 accord auto. The shifter has been sticking for a while now meaning its hard to put it in park or take it out of park to drive. Yesterday I went to put it in park and the shifter went into park but it didnt actually shift into park. The car is like is in neutral. All the other gears work but no park. And now I can't get the key out. Is this just a shifter cable adjustment issue or could it be something else? How do I fix it?
