    Is there such a thing? I was thinking it would be like a doubler but instead of increasing the gear ratio to the rear differential, it would decrease the gear ratio. I have a th400 with a BB 454 and my gas mileage sucks. I'm asking because I have to drive at least 200 miles to go wheeling and motorcycle riding. I was hoping there was a cheap alternative to a built 700-R4 or Gear Vendor overdrive system.
