last night I was driving on the highway with slippery winter roads and my 2000 Ford Focus (automatic transmission) slid/spun into the side ditch. Problem now is when I start the car up and put it in drive or reverse with gas pedal(like normal city driving) down it won't move(but I could hear fuel is being fed into the engine because the engine speeds up). Now, if I push the gas pedal almost all the way down then it moves like 20-30km/hr. Any suggestions on what is wrong with it? Thanks for the help!
