Transmission problems with Ford Edge 2007?

What is your question?

I stopped my vehicle at a red light, and when I pushed the gas to go, the car felt like it was in neutral-my speedometer stopped working, the wrench light and airbag light came on, and it make a huge thumping sound like the transmission was going to fall out of the car. I turned the car off, restarted it and the car worked fine. Anyone else have this issue and if so, did you get it fixed?
