I know the term gas milage has no place on a performance enthusiast board but I DO have to drive this thing from boston to woods hole or portland on a fairly regular basis, so how much of an impact would a 2500 rpm non lockup have on milage compared to it's lockup cousin?
What exactly is inside one of these shift kits anyway?
