My chick has a 2017 and the ratios on the 9spd are stupid tall..... totally the wrong setup for NA. I don't drive it a lot, but I doubt it uses the last two gears very often if at all....I had a 2015 jeep cherokee with the 9 speed auto. That thing only shifted into 9th gear when I was doing over 100 but it wouldn't hold it.

This. TFL tested(yeah, I know their tests are far from perfect) the Ram 2500 vs the Silverado 2500. On paper, the Silverado beats the Ram with 75 more hp, more low end torque, and a modern 10 speed vs the ancient 68RFE 6 speed slushbox. But their 0-60 showed it to be 0.2 seconds faster than the Ram, and the Ike Gauntlet towing test showed the uphill climb being identical, and better engine braking with the Ram down hill. I'm wondering if it's just poor transmission tuning on the Duramax, or bad drivers.It is interesting to me how the "more gears, more better" thing has gotten to the point it has. Because modern engines seem to have a MUCH better overall ability to apply power over a much broader RPM band than they used to, even diesels.
I agree. This also means any time the power demand changes the transmission shifts, sometimes multiple gears "Just pick a gear and stay there!"It is interesting to me how the "more gears, more better" thing has gotten to the point it has.
