When I put the car in gear either way D or R from a stop, only the first time, it makes a strange noise. It sounds like a clunk ormaybe it could be described as what an old u-joint sounded like.Could it be the exhaust hitting ? If I put it back in park and try again, nothing. If I move the car and do it again it will make the noise. Maybe something id hitting or I really have no clue, It's definitely not a normal noise . Or is it ?????????
