Hello XC70s, My 07 is high mileage but run very good, one issue that I don't know if it's normal or it tell me some thing? When I put in reverse backing out my driveway it's OK, but when I stop to wait for traffic it seem like the transmission is vibrated, I don;t recall if my other cars were like this. Is it normal or there is a symptom of some issue? I appreciated for any comment.
