I need your help! My son has a 1997 Honda Civic LX automatic approximately 90,000 miles. When starting up from a stop on a dry road the car does not seem to go right into gear, very strange but it is almost as if the tires are spinning as if you were on snow or ice and a slight vibration. Then all is fine this problem only happens from a dead start not if you slow down and then accelerate. Anyone know what may be going on?
