Hello guys, I am a newbie to this forum and to cars in general, so please bare with me. Today I was in a hurry and accidently put my Honda Accord 2007 (automatic) in park (shifting past reverse) while the car was still coming to a stop, this caused a loud grinding noise. When I put the car back in gear it jumped (equivalent of letting go of the clutch too quickly on a stick). Could this have caused any internal damage? This is the first time it has happened, and it's a new car.

Sorry if I sound stupid, the sound just worried me :)

Could have. If any metal shavings got loose the filter should have gotten them though. If you're really worried, have the trans flushed and filled.

Its not good to do that of course...LOL However I think what your heard was a safetly item made to break away like that.. Probably sounded like a really loud ratchet sound?
