general problems of the 2004 Ford Thunderbird

Driving on a highway at 50mph coming to a town and a red light I removed my foot from the gas pedal and applied the brakes the car did not slow I applied more pressure on the brakes the car slowed some but the engine kept reving the transmission was not down shifting the car was not stopping I grabbed the shift lever and switched gears but to late and we hit the car in front of us stopped at the light.

As I was parking my car, it suddenly accelerated at a very high rate of speed. I was parking by a wooded area, and was propelled about 2 car lengths into the bushes in the woods (barely missing a tree) before I was able to stop the car. Not certain if the car stopped because of my braking, or because the thick bushes would not permit the car to travel any further. I had the car towed to the Ford dealership, but the service dept. Has not been able to find the problem. I am absolutely certain this was not a "driver error" situation and am very concerned about continuing to drive this vehicle should this occur again and I hit someone or something less forgiving than the bushes in the woods.

Tl- the contact owns a 2004 Ford Thunderbird. The contact stated that while driving approximately 45 mph, the transmission would not shift correctly and exhibited a severe hesitation. The vehicle was driven to a nearby transmission center where the contact was informed that the transmission would need to be replaced. The vehicle was not repaired. The manufacturer was notified of the defect. The approximate failure mileage was 55,000. Kmj.
