Also, it's known that the C6 6-speed was internally modified from the C5's design. Does the CTS-V have the C6 internal design or the C5's? It seems, at least to me, that the C6 6-speed is in it's first year of production as is the CTS-V's.

Six speed.
Six speed.
Anyway, the 2004 CTS-V which went into production in January, 2004 has the tremec 6 speed and is still in it's first year of production just as the C6 is in it's first year of production. My point is that both are experiencing first year teething problems.

"Changing gears
The 2005 Corvette continues to offer drivers thrilling driving dynamics, whether they prefer shifting or leaving it to the transmission. The Tremec T56 six-speed manual is standard and the Hydra-Matic 4L65-E four-speed automatic is optional.
Corvette engineers thoroughly revised the Tremec gear box and added proprietary technology not offered on other automakers’ high-performance transmissions. The six-speed transmission also has revised gearing when selected with the Z51 performance option. With the Z51, the Tremec is tailored with numerically higher gears to improve acceleration. Also, a lower fifth gear gives the Z51 better fuel efficiency and a higher top speed than base models. To increase durability in sustained high-speed situations, the Z51 and the base European manual-transmission models have a transmission cooler.
Smoother shifting six-speed
C6 Corvette drivers will find more pleasing, performance-oriented shifts with the six-speed transmission. They’re smoother and more precise, with shorter overall throws. The gear shift lever is now an inch shorter, and travel for all synchronizers is reduced by 10 percent. An all-new shift linkage and shift-rail bearings contribute to a more positive, confident feel. Computer Aided Gear Selection (CAGS) continues as a fuel-economy enhancement function for the manual transmission."
