I opted for a 700r4 transmission over a 400, to get the overdrive feature and I hope save gas and more highway friendly.

Other than manual transmission, 3 or 4 speed, most would say the straight 6 is the most economical to drive. I am a fan of the 700r, uncertain as to mounting to a 6 cylinder motor. Maybe some company makes an add on overdrive for the powerglide. The best I think you could get was to drop the rpm from 3000 to maybe 2200.

4.11 gears might help.

Changing rear gear ratio, might get you to around 2000, maybe.

Until that power glide gives up the ghost, I would keep driving it. Once it does, you might have some options that might get you more Mpg.
