Thanking any responses in advance.
My 2014 SS M6 is real noisy especially on 1st to 2nd gear shifts. When I first bought the car this was very alarming. Went in to the dealer and the driveline specialist walked through what was making the noise.
He pointed out that the giubo couplings on each end of the driveshaft are designed to absorb a lot of energy when loaded - like storing energy in a rubber band, they are huge rubber pucks:




When the energy is suddenly released (during manual shift) the giudo causes the driveshaft to rotate quickly and slight play in the transmission gears causes a clank (Tremec TR6060 in the case of SS). I've read that the Tremec is designed to have some extra play in the gears due to expansion when heated and for high speed use.

We rocked the tire back and forth sharply, quickly changing direction when the car was on the lift, and sure enough could hear a clank from within the transmission.
Listened to all points from the differential forward and the only location I could hear noise was in transmission. And no noticeable extra play at other points.
He even checked torque specs on bolts and made sure transmission fluid was at correct level.

After a month of driving I re-learned how to load/unload the drive train while shifting and what rpm's are best to mostly eliminate the noise.
This is the toughest transmission/driveline to shift out of any manual I've owned. Most shifts in everyday driving I can now do without noise.

Due to high HP these energy absorbing giubo couplings are used to help absorb shock and keep things from breaking versus using a plain universal joint.
