Just got the results from dealership. The reason why my 2004 GT was lunging was because the torque converter broke. There was so much damage inside that Ford decided to replace the transmission at MY cost since the car was towed to the dealership on the last day of warranty and they logged it in for the next day, which would be one day after the warranty. I'm the classic little old lady with low milage that doesn't drive much and I don't know how this happened to my car with only 29,000 miles. Anyone care to address this situation, it will be appreciated. Also, what gives about the warranty? Does it go by the hours of operation of the service department, or 3 years til the end of the day?
