so you're saying a built 6spd Allison is a better bet to have for fuel mileage than a zf6?
Why does it have to be built?

I know im splitting hairs, but think your tach might be off...80mph, 3.73 gears, 35" tires, .74 6th gear is around 2150...and thats provided your tires actually measure to a TRUE 35". (which 315's dont).
Regardless, even a 5-speed allison will still have a lower cruising RPM than a ZF6.
Did I mess up by not buying an 04 rclb 4x4 with he zf6. 200k for $3800
I just saw an Arrival Blue ECLB '03 ZF6 listed locally.
