tranny does run hot. an aftermarket cooler is a great start. doug thorly headers are available for a pretty penny. not many intake choices out there. there are alot of ls2, ls6 parts that swap over with little modification. triple edge performance does good trans builds, cartuning makes a turbo kit for our cars that makes rougly 500 hp. one of the cheapest things you can do right out of the box is wrap the crossover pipe with heat wrap. reduces the underhood temps quite bit.
