This past Tuesday, I was coming home from skiing and went into a ditch on the right side of the road. The front end of the car was filled with snow and I had to get a tow truck to get my car out. The tow truck pulled it out from the front end. Before I left to drive home in the same car I cleared most of the snow out of in front of the radiator. The car was working, but I had to take it slow to prevent the engine from overheating because of the snow build up. The day after I toke it out for a drive and noticed a loud humming sound when driving faster than 35mph. I think that the car isn't shifting into overdrive. Am I right to say that the problem is with the overdrive? And what can I do or check to fix it? I intern at a dealership and I am going to take it there around 5:30 today. Thanks
