I just purchased my 2010 C14 in July. It jerks between 1 and 2 and 2 to 3 no matter how slow I let the clutch go. It's so bad that I don't use the clutch to shift. The mechanic at the dealer said. It will go away once I start using synthetic oil. He said to wait until I have 5000 miles before I switch oils. Anyone else has the same problem. Thanks.
