I just tested mine and I have the 2nd gear grinding problem... It has done it before a couple of times, but even though I've been driving manual cars for years, I thought my left foot was just getting slow. I was driving out of my neighborhood at around 20mph, put the clutch pedal to the floor, then shifted fast into 2nd. It went into gear, but horrible grind like the clutch wasn't even disengaged... Then I did a 3-2 shift. Same thing. The trans temp was a little past 30. I pulled into the store parking lot (trans temp between 30 and first line) and made a few 10mph laps around it. I tried multiple 1-2 shifts and it made the same grind every time. I then drove it back to the neighborhood (trans temp just past the first line [110?]), tried it again, and it went into 2nd without a problem. The reason I tested mine was because yesterday I took a straight side road right after leaving my house and hammered it. Ridiculous grinding on the 1-2 shift at high rpm's as well. It seems in every situation, my trans temp has been between 30 and the first line (105?). Should I drive straight to the dealer tomorrow, wait until it cools down, then let them try and duplicate it? Or is there nothing wrong and I should just let the darn thing warm up before driving it like a Camaro SS should be driven. I mean, I've shifted lightning fast with every manual car/truck I've ever owned and NEVER had a problem, cold, hot, or otherwise...
ALSO: Mine is a 2011, has just over 1,100 miles and the last numbers of my VIN are: 134441. (Build Date 10/2010)
