3.31 gears at 40,000 lbs gross.
Just to give a bit of a feel for how different gear ratios would behave while towing I locked out 10 then 10th and 9th then added them back again while travelling on a straight stretch of road w...

I obviously don’t know the stats but could it be that 999 out of a thousand Powestrokes are equipped with either 3.31 or 3.55 gears so the likelihood of coming across a 4.30 equipped truck with problems is not very likely?
No, no, you are right.... The added stress of towing the same load in the same gear with a 3.31 versus a 4.30 does nothing to the friction material of the clutches or decreases the life span of the transmission. Just like the added stress of towing does nothing to the friction material of your brakes and anyone who tows all the time should expect the same life span as one who never tows.
Why would I be in the same gear with 4.30 gears vs 3.31 at the same speed. When I’m towing hard in overdrive with 4.30 gears I’m in 7th with 3.31s.
