4X, how much do you think these 10 speeds help with the Diesel engines compared to their previous 6 speeds? Lets say the Ford with todays HP/TQ with 6 speed would it do as well as the 10 speed or???

It will do better in a variety of situations compared to the previous version. This does not equal better in any one or every specific test.

If you focus on one test as a proxy for usefulness you are missing the bigger picture of technological advancements.

I agree, I was curious his opinion on that specific situation.

I guess my thinking is how much of the time are we using all these gears, do they make much of a difference?

Cruising down the highway in high gear 6 or 10 speeds any difference?

Pulling a 6% grade for 5 miles make much difference? Once you are in your gear at a given grade that does not change.

To me the fact we have/had 6 equally spaced gears was the most improvement we all have seen. Now "I" think most of it is advertising and not that much is to be gained.
