2000 Honda Accord problems after wreck

I have a 2000 honda accord ex v6 with 107000 miles on it it was in a wreck a month ago still have not got car back but anyway I got hit on the drivers side from the headlight all the way to the drivers door and the middle of the hood. The hood crunched all way to window. My airbags did not deploy I was traveling about 60 miles an hour what could be the reason they didnt deploy? Also, before wreck I had no problems with trans. I went to go pick it up from getting repaired and I asked to drive it to make sure everything right the man asked me if I had a shift kit on it I told him no so we get in the car and he cranks it and the check engine light is on and the d4 lite flashing while in park. He put it in reverse and I thought the motor and or trans fell on the ground it jerked so hard so he back out and put in 1st gear I never had to drive car in 1st I ask why he said because it wont drive in d4 or d3 at all. He told me they would have to take it to honda and get them to put on a diagnostic machine to see what was wrong with it. On the way to honda the car broke down because the alternator bracket broke and it has been sitting at a honda place for now 3 weeks they said they would have to call an engineer to see what the problem was! Can anyone anybody please please help me and gimme some suggestions of what could be wrong I had a trans service in 06 and have it checked when get oil change everything fine no leaks and nothing wrong until now. Please help me
