LS4 Front-Drives 2005-2009 - How much does a tranny cost?

I'm thinking about getting a grand prix gxp and wondered if I blew the tranny how much a new one costs and do they make beefier ones? thanks for any help. Also do all years have dod? I thought 05 didn't.

Dunno how much they cost, but you can always beef them up a bit, cheaper. And all LS4s have DoD.
