Changing from 3.73 to 4.10 gears
Hello all, After towing our new Reflection 320MKS from Eastern Iowa to Estes Park Colorado and back, I need more power for the hills. I have a 2015 F-250 with the 6.2 Liter engine. I have 3.73 years...

Spot on and add two more attributes
There is one more torque multiplier if there is an automatic in this food chain of torque from the ICE to pavement...TC's have a torque multiplication factor in the average range of 15%-20%, so your formula below needs to have that additional torque factor...until the TC locks up...then that slippage/multiplier goes away
Other is that today's computer control system has 'torque management' as one major control factor in how much torque is allowed to be delivered
Why with today's levels of power...smoking the tires is tough to near impossible to do

Torque matters.
All of the Diesel guys are debating when the TQ numbers will go over 1000, and which brand will do it first...
Let me show in simple math why the engine race isn't all it's cracked up to be.
Lets say your motor has 500 TQ.
And your 1st gear is 6 to 1.
You will have 3,000 TQ!, leaving the tranny.
If your differential ratio is 3 to 1, you will have 9,000 TQ!, to the rear wheels.
If the diff is 4 to 1, it will be 12,000 torque!!
These are BIG numbers, so big that it makes the manufacturers adding 20-50 #s to the motors, seem like small potatos.... Of course an extra 50 TQ would mean an extra 900-1,200 to the rear wheels.
That is the secret magic of gearing.
