The sixxer i had was auto (all i could find, she was pretty), the first thing i did was bought a sct livewire tuner, (it had just hit the market). I agree with JKs95stang when he says thats what you prolly want, its quick and easy power( an advertised 15 hp an 20 tq), and the car Kicks every shift. Sooner or later tho you will want a stall converter, especially if you take her to the strip.
