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...

If it worked the way you said then the manuf would recommend that to tow a certain amount of weight you would lock out Ome of the top gears for that particular weight rating!
Effectively, that's what they are doing. They just do it automatically. If the truck can only hold 8th gear, it won't use 9 and 10.
You are seeing fewer rear end ratios available and they tend to be lower (numerically).
The main reason to consider a higher (numerically) ratio is if the lower ratio doesn't have a tow rating sufficient for your trailer. If it's within the tow rating, the transmission will effectively lock out a gear or two so the overall gear ratio keeps the engine happy.
Yes but the engine and trans are working harder in each of the gears with wrong gearing!
Why is an automatic in the wrong gear ..... I guess it would be in the wrong gear if someone has 4.30 gears to pull a 20,000 lb trailer and the engine has to spin 1900 rpm in 10th because the tranny can’t upshift anymore? That would be wrong gearing.
