You should be ok unless your tranny is going out right now. 415 crank HP is not that much abuse on that tranny, change fluid every 50k and install aftermarket trans cooler and you're good to go. But yea-if you want to use evey bit of your newfound power the 6 speed is the way to go , but I like my auto with the supercharger .
