I found this site checking to see if this exact thing has happened to any one else! This weekend, on a road trip, AZ. desert to Tucson, 4 months owned and 4000 miles, a possible puff of smoke or wet road, looking back, definitely smoke. Downshift to pull over- no gears. Gearbox oil all over and smoking badly. 2 hrs. in 100 degree+ desert waiting for flatbed tow truck to take us in to Phoenix. Diagnosis- drive shaft 1/4 inch out of gear box on left side. No bolts or bracket! Everyone have your dealer check this! AND, Ford does not provide a rental replacement!!!!! FORD GT, Found On Road Dead, Great Truism. If it is just the two of us that's a .05% failure rate of a potentially fatal failure. Ford, do something! I'm providing copies of this thread to Ford.
