3.42 gears for TC
Hello, Just looking for some thoughts on pulling hills with 3.42 gears. I'm going back to a pop-up TC @ 1800 lbs dry weight. The trucks I'm looking at are the Chevy and GMC 3500's SRW 4x4...

Ok, I get it - there’s no way to justify a 4:10 rear end (even with 2-3 OD tranny ratios…), and no reason for a manufacture to offer one on their order list - I truly had no idea that increasing the GVWR and the towing capacity was just a marketing thingy (heck, who knew!!), obviously I blew it (dummy me - lol), ‘one ratio for all’ is now starting to make more sense than ever, and who knows, maybe even the manufactures might read this, recognize their goof and rethink the ‘perceived magic’ of costly 10 speed trannys with OD??

While I recognize your sarcasm here, let me add some food for thought:
It's stronger and easier to gear down than gear up. That's why the 10 speed offers 7 underdrive gears and only 3 overdrives, instead of 3 underdrive and 7 overdrives.
The 3.42 gearset in the axle is also stronger than the 4.10 by virtue of the larger, deeper teeth of the gears.
What I love about this conversation is how many "converts" there are now to the new way of thinking. For YEARS, I tried to get people to abandon the church of "Our Lady of the 4.10 Gearset" by virtue of the then-common 6-speed transmission and was called all kinds of names for it.
