Referring back to those BSFC maps I posted, if we want the absolute best mpg, then there's only a small windows (dark blue), between 1500 and 1950 rpm, and 55% to 90% torque output.
That's where a 10 spd would be beautiful.
Roy I think the 3.31 rear end and 5th gear with the Aisin would be hard to beat when towing heavy and when towing light or running empty 6th with 3.31 gears is tough to beat. To bad they did away with 3.31 gears.
