I would be on the safe side. I have a 99 Contour SE Sport. It only has 21,000 miles on it (dont' drive much), and I think I am gonna get it changed for a metal one at 30,000 miles just to be safe. I have to have transmision pan change and some other stuff so I will have them do it while the car is in for service. Does anybody think I should wait? I would definately change at over 100K miles from what I have heard.
