Assuming the motor will be covered under warranty, I'd do 2 things that are relatively inexpensive in parts but will kill you on labor to R&R the tranny: torsen/quaife (your choice) and new clutch. Usually if you provide those parts the dealership will install them for just the labor without the tranny R&R, but talk to the service manager first. Other than that, make darned sure you get a replacement SVT motor and enjoy your "new" car.
