Alternator/generator/regulator problems of the 2003 Mazda MAZDA6

My car has had all of it's routine maintenance done. At 30k I had to replace the transmission at 20 I had to replace the alternator. At 60k I have had to replace the transmission again! at 60k I had to replace a transaxle something or another . Now at 66k it is doing all of the same things that it was doing before the transmissions went out, and it's because "I need a new air filter, spark plugs, and fuel filter" the car jerks very hard when slowing down on the freeway the rpm race, like it won't gear down. When I put it in park it's as if I am pressing the gas pedal down and revving the engine. But the car is in park, and there is no pressure on the gas pedal what so ever! I hate this car, and recommend no one to buy one! I will be voicing my opinion of the car in the car windows, and telling everyone I know about the poor quality of this car. You would think that paying 27k for a vehicle that it would last!.
