i am looking to put 3:73 or 3:55 gears in my automatic 1990 SC and i was wondering is this something i can do. if so how easy is it or would it be better to take it somewhere to have it done. if so what type of place should i take it? the dealer? well any info on this would be great. oh and by the way which gears will i notice the most performance gain with? thanks
