when i had my old 56 chevy i blew a rear end every month . I used up every one the junk yard had . Went from 3:08 to 4:56 and I could tell what I had by my MPG and my RPM in 3rd. (high gear) and they were strongly related

A MT will have better mileage because the torque converter in an auto slips when accelerating and sucks up gas and power.
