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??

Sarcasm indeed! Marketing? Well aren’t most new things marketed? That’s just business.
I know you’re not accepting of this and consider it to be some charade. But that’s ok. Maybe it will spur you (without admitting it of course) to be more well read….Or maybe it’s easier to just keep talking about how back in your day you had to walk 5 miles uphill to school both ways, in the snow, and if only the bus had 4.10 gears, life would have been different! Lol
On a serious note, it’s a balance between available power, available trans gearing, and strength of components.
I mean, why does GM only offer 3.42s with their diesels and now only 3.73s with their Hd gassers ( which is a mistake. They didn’t take a step forward in the gasser market at all with the new 6.6…dunno why) when Ram offers 4.10s in both and I think ford goes up to 3.90s but a standard 3.31 behind the diesel?
1. Ram is still using old outdated transmissions. A signature move for …ever now. Not sure why.
2. Ford, idk, maybe they figure their trucks are strong enough to handle the power, 10 speed deep gearing and deeper rear gears.
3. GM, idk, they’ve always only offered 1 ratio behind a Dmax. Simplicity in mfg? No need for deeper gears? Who knows and who cares?
It’s the principles in design here that are being discussed. Take the names out of it. But until you understand the engineering principles, you’ll continue to show your butt while defending your position, which happens to be with your pants down….figuratively speaking of course…I hope!
