The 6 spd is not an overdrive transmission, it just gives more ratios from 1st to 6 to pull heavier loads.your cheapest bet is to put on taller tires.I'm pretty sure from your posts you have 3:55 gears.If you had 4:10's I'd say put in a Gear vendors overdrive,I have onereally helped me for interststate driving
