But I heard enough of the clunk noise this morning to say my post #14 stands. I've heard this noise in other manual transmission cars, to a lesser degree, but under the same conditions. That is applying and releasing torque to the driveline. In my opinion it is the sound of gear lash. I do however have a theory of why it is more noticeable in the Solstice. First, the transmission is out of a truck, so the tolerances are probably somewhat wide. (It's also probably strong enough to haul a motorhome out of a ditch.) Secondly, it's all hooked up to a super rigid platform, that in effect gives the driver a more "close" relationship to the driveline. Add these two together, and this noise could be the result.. Again, this is a theory, but for now, it's my best guess of what's happening here. I really don't think there is a durability issue at all. Rest assured if I find out anything new on this issue I'll post it. And thanks to everyone else that has researched this concern, and posted. windface.

This makes the most sense!

I have noticed though as I have perfected my shifting more that I hear it much less.

Was this clunk heard on the prototype? Before the car it the market did anyone from GM hear this? It would be interesting to know.

Personally I think it is going to be a given for this roadster and in a way it could make it even a little more appealing because it gives it personal character...after all what makes something unique is what makes it different. If the Clunk is not a problem, but just a by product of how this transmission is designed with the gear lash then no worries. Truthfully I am getting use to it. It such a fun car to drive!!!!!!!!!!!!!
