I have a 2003 Honda CR-V EX with 175,000 miles. I just found that this morning that the automatic gear shifter is loose after I release it from Park. I can still be able to shift to Drive, Neutral, and Park as before. Fortunately, I'm still able to drive. It is sturdy and tight as it should be at Park, but loose with the other gear selectors. I think it may be my brake is loose. What to do?
