Low Milage newer vehicle, bought used. Have only put half the miles on it. If it is Clutch at 15k miles that should last a lot longer. if it is transmission Ford should have known better than to take out the steel and substitute aluminum in a high performance car. Do not get me wrong, I am almost 50 years old, I do not beat my cars, I take care of them. My last car I traded on this was a 2008 Corvette.
