ok i have an auto tranny with the stock 2.73's i wanna replace them seeing as how i have some pretty decent mods i think gears is my next step. this is my daily driver so i wanna keep it mild. which size is recommended? and also who should i buy the gears from?

 

3.42s from a stick car work great for a decent pickup on a DD and don't effect fuel economy very much.

 

I lost two miles per gallon when I went from 2.73 to 3.42 but the SOP went way up so it was well worth it to me.
