Does anyone else experienced a shudder when the C7 shifts from overdrive to passing gear? It is a very hard shudder that makes such a hesitation or shudder that the passenger can feel it. It does not shudder every time but about 80 percent of the time. We went to the Tail of the Dragon this past weekend and it shudders every time while ongoing threw the mountains under all driving conditions. It also does not matter what position my driving dial is positioned in. Any one else with this bug?
