I parked on a decline today and when I put the car into Park I noticed it was hard to do and the entire gearbox cover was flexing. Never seen anything like it before. The car did go into gear when I left, but when parking at home (flat surface) it was more resistant to going into Park than usual. To me, it seems like there is a loose bolt that needs to be tightened, but that is just a guess. Anybody else have any thoughts or has experienced a similar issue?
