My Car has 93k miles. I am having trouble with my transmission shifter.

What is your question?

When I drive my car and then come to a complete stop to park. When I move gear shifter from "D" Drive to "P" Park, it stops at "N" Neutral and can not move past to Park. I wait a few seconds and try multiple times and it will eventually go to Park. Please let me know what you think is causing this problem. Thank you.
