Ok so I was coming out of the gas station trying to make a left turn this morning pretty hard to get ahead of traffic and my car starts bucking. It's not too bad at first but now I can barely drive my car in first or second gear. Especially if I'm trying to make a left turn in first gear it starts bucking really hard like I let off of the clutch really fast and it's almost like the transmission is slipping. Right turns are not too bad and when I'm driving occassionally it'll buck like the fuel pump is bad, which I guess could be another possibility. But there is a sharp metallic sound when it bucks like metal grinding on metal or gears slipping. Any ideas? I drove it pretty much straight home after it happened and it was ok to drive as long as I was going straight. The dealership is closed today, but hopefully they're open tomorrow even though it's a holiday and they can take a look at it. Any help as to what this might be would be greatly appreciated. Thanks.
