My 04 GT, my 04 Cobra, my 07 C6, my 09 GT500 and now my 11 GT all had a notchy and sometimes light grind when cold. It takes a few miles for the fluid to get a little loose then it shifts like butter. This is normal for all manual vehicles...... WTF.
i would agree with you, except that my car had absolutely no notchiness or grinding when it was new. even when completely cold. NONE! it shifted flawlessly which was part of the reason i loved the car so much. it has slowly gotten worse and my car only has 1300 miles on it...
