How much did the different transmission ratios help GM?

Where would they each be if they put their best performer out there? Example RAM's 4:10 VS 3:73?

Why not show the best of what they each offer?

I thought about that too, but the GCWR's are all pretty dang close so it's still a fair comparison.

Maybe that's why Ford feels it has to use the F-450 to compete against the 4.10 Aisin Cummins.

The 6R100 is lower in every gear than the other two transmissions. The don't even have a direct drive, 4th is 1.14:1.

If you compare the final drive ratio in each gear between Ford and Ram, and you give the Ford 3.73's and the Ram 4.10's the Ford is lower in 2,3,4, and 5th. So a 4.10:1 Ram is only lower than a 3.73:1 Ford in 1st and 6th, no wonder it's quicker off the line.

3.73's are the only GM option.
