So, after reading through most of this post, I'm realizing that the grinding sound I keep hearing between 2nd and 3rd (after the transmission gets warm) is not in my head. Lol. I first started noticing this around 450 miles and it got really bad at 650 (it's more consistent now). I'm supposed to take it to the dealership I bought it from (150 miles away) Monday (12-3-12) to get looked at, and am hoping they don't tell me this is normal or some other line. Anyone have suggestions on what to tell them is going on? I suppose I could point them to this forum.
By the way, it's a 2013 titanium, with 705 miles as of right now.
