i was going down my street and was in the process of shifting into neutral... i was just rolling like 20 mph.. and i hit a bump.. which made my hand shift into reverse on accident... i herd a loud sharp noise that sounded like my tires chirped. and my engine shut off.... after coming to a stop. i turned my truck back on and drove into my driveway... its not smoking or leaking any oil... do i have anything to worry about?????
