The tranny is a Tremec TR6060, a derivative of the T56. It is the same tranny (according to Wiki) used in the 2007 GT500, 2008 Corvette, 2008 Viper, 2009 Challenger, 2009 G8 GXP, etc.
There should be NO reason we cant rev to 6000 RPM and dump the clutch. You dont think any owners of those other cars do that?
The tranny isnt the problem, it has to be something specific with a certain batch.
