Don’t know how to reply to this question?
I have a ISX15 400 that’s been bumped to 480.
I have to get back into the truck next week to answer this question.
Thank you for replying !

What I was referring to was when you run out of power in 8 ,you shift to 7 and so forth . Think of your rear end ratios the same way .
Why do heavy haul guys or off-road guys run lower gear ratios?
When you sling more weight or hard lifts in soft ground you need the mechanic advantage.
3.90 will out pull 3.55 big time with the same motor . OR get better feul mileage due to not working the motor as hard even on flat ground.
You need to decide if you want to run at 80 mph or 60.
