Yesterday I heard a clunk like sound when I put the car in gear but didn't think nothing off it. I was on a hill so it was just the pressure of the car coming out of park. Well this morning on the way to work everything was fine. I get about 8 miles in and soon as I attempt to pull off from the stop sign the car moves and then I hear this sound like gears grinding. I immediately come of the gas and let the car coast to the side of the road. I slowly push the pedal again and hear the same sound. I cycled through drive, park, neutral and reverse and the gear shift moved normally. If i put it in reverse I hear the same sound, same sound in drive now without pushing the pedal. I'm on my way back to get it towed but from looking under the car I could see nothing that looked out of place. Trying to get any info that will help me when I take this thing to the shop
