Transmission Noise problems of the 2005 Honda Accord

Car was running fine. No problems. All of a sudden the airbag light came on. I stopped the car and checked the seat on the passenger side and seat belts trying to figure out why it was on. I got back into the car and continued home. When slowing to turn into driveway a loud banging noise occured. The car was put in park and immediately started rolling backwards. This could have been a hazard if a car had been passing by or if this had happened in busy traffic. I could have rolled back and hurt someone, hurt myself or rolled back into oncoming trafic. Also if someone had been walking behind the car and gotten ran over and killed. Anyway it was later towed to a dealer and diagnostics ran. The dealer informed me that I needed a new transmission. That is not right. My car was like new with a little over 68 thousand miles on it. I still owe on it and purchased it brand new. Honda should be responsible for this. Since this has happened to me and I have begun to research this I found a ton of recalls for this same problem, yet I am told my car is a 6 cylinder and is not under recall. Please help. I was told it would cost me 4400 plus $ to replace the transmission. Honda should be responsible for this cost.

On April 2 2005 I bought a Honda Accord. Recently I took my car to the ourisman Honda dealership for a routine maintenance. The previous day I heard a noise coming from the engine. I explained to the noise to the technician. He checked and found the car had a problem with the transmission. He told me that they were going to try to talk to american Honda to help me out with the cost because it is very expensive. It has been three weeks now with no response. I would like a solution to this as soon as possible. Any help from you would be very much appreciated. Thank you for your time. -martin quiej.
