Ford needs to update their transmission to make better use of the engine's torque for optimal performance. There's no reason why this truck can't at least match the GMC's performance under a load.

I really like the truck's tech, road manners and interior room.

They just need to reprogram it

also wood like to know what gear ratio they had in each

Sounds like the GMC scored a hit with the judges.

The Ford camera tech was praised but the GMC was rated superior for key considerations such as acceleration and performance, as well as handling and comfort.

I've heard the 3.73 is the lowest gear GM offers with a diesel.

You are correct. With the power and torque produced by the Duramax along with more efficient transmission, there is no reason for lower gearing.

Hearing you guys talk, I can't figure how the Ford won ? Really the GMC seems to win in all the important caterogies, pulling, engine, transmission, driving... does the interior carry that much weight in the rating ?!

Yes. 4.10's are more gear than the Duramax/Allison need for it's tow rating and tire size. If somebody wanted 4.10's to help with big tires, the ring & pinion are available online.

Just look for:
AAM 11.8" 14-bolt 4.10 30-spline (12 ring bolts) gears. The front 9.25" 4.10 R&P should be widely available.
