Car starts and drives fine but after I get up to around 60 or more it feels like I have a flat tire like a loud banging noise from under the car and feels like that until I stop . If I put it in park and then go again it goes away until I get to a higher speed then it comes back ,and if I keep driving with it banging it will eventually go away but comes back at times randomly? Any idea to what this could be? I know there was a little weight thing that was hanging off of the transmission that got ripped off ,would that cause this?
