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 wouldn’t say “who cares?” But I think it is an honest question to say “why would a person care?” Will the Ford driveline last longer transmitting 200 hp at 2400 rpm than it will transmitting 200 hp at 2000 rpm?
Yes, the transmission will have a much greater chance of lasting with shorter gears. Just about every 6R140 through our nine Ford dealerships with burnt or grenaded overdrive clutches was with a taller gear ratio and/or heavy oversized tires.
If what you’re saying means anything it would lead me to wanting 3.31s in an f450. You need to think about what you just wrote.
Shorter gear ratio = higher numerical number. Taller rear gear = smaller numerical number. This is the basics of truck ownership(especially if you own HD trucks) and I am not sure how you are getting confused.
You are saying the overdrive clutches have grenaded and I presume you are claiming the clutches can’t handle high torque. People with new F450s are claiming they can tow their 22000 lb 5ver from here to Kingdom Come and they might drop to 9 th gear on the odd hill. Oh boy ..... those poor overdrive clutches are taking everything that Powerstroke can throw at them.
When I’m towing heavy with 3.31 gears I lock out 9 and 10 and when I hit the hills I’m in 7th.... 1:1 ratio..... perfect.
