+1 on the 1st to 2nd notchy shifting. Yes, it has even grinded gears during spirited driving too. I took it to Connell Chevrolet in Costa Mesa and they said, "It's operating as designed".
What a freakin' joke! That's is just pure laziness! Now it's at Selman Chevrolet in Orange. I hope they step up, thoroughly investigate and fix the problem. To me it feels like the clutch does not fully disengaging and has worn the synchros. What's strange is it's notchy whether I'm sitting in the driveway with the engine turned off or driving.
Here is a video of the notchy shifting:
Here is the pathetic worksheet from pathetic Connell Chevrolet:
You saw the video, right? So how can Connell Chevrolet be so oblivious?
