09 Challinger 6 Speed Tran

Can anybody tell me the specs or any info on the 09 challinger tremec trany.
i have found one from a 09 6 speed. he says its a t6060 and gave ne some more numbers, but it does not have the slip yoke on the tail shaft but a three bolt flange. that would be kind of tough to install with out a slip joint in it some place for rear end movement. Also what kind of power can this boy take, ? if its the same as the viper trany i am ok with that. any help
Thanks
Roger
