Driving at 45 mph ,transmisson shifted with a jerky motion ,first started then. When you first take off it jerks and makes a noise. When you back up it jerks hard enough it wips you body back. Had it checked at a transmisson place. They tore it down and found nothing ( $400). Still jerks and shifts rough. Don't know how long it's going to last.
