Axle Ratio and tow rating
I was looking at a 2014 Ram 2500 with 6.4 Hemi the other day as a possible tow vehicle for my 5th wheel (9100lbs dry) so I looked up the tow ratings. With the standard axle ratio (3.73) the truck is ...

I'm just trying to call it what it is. The power doesn't change. You just swap rpm for torque.
That's how the 400hp turbo-diesel climbs the hill at 50mph in 4th while the 150hp hot water six in can only make 20 mph in 1st. Gearing down won't give the diesel more power, it would just slow it down.
Simple example you need to torque a bolt to 1000 you use a 10 to 1 multiplier so you only have to exert 100 ft lbs to get that torque. If you go to a 5 to 1 multiplier you would need 200 ft lbs to gain the same same torque.
The lower gears affect every gear all the time. Diesels have to be geared different than a gas motor because of their rpm operating range, gears that work for diesels aren't the best for gas motors just like gears for gas aren't the best for diesels.
