Gear Ratio for TH400
I would be interested in opinions for a good rear gear for 12 bolt rear end. I currently have a TH400 with no overdrive and 3.73. I do drive frequently on the highway and am turning 3000rpm @ 55-60mph. I would like something that's easier on the motor. It seems the highest I can go with a 12 bolt is a 3.08. Is that correct?
