Will my truck tow safely in the Smokys?
I have a 2017 Silverado with max towing of 6100lbs, it is a 5.3 w/ 3.08. My TT is 5000 lbs dry. My Truck feels strong enough on flat land but I've never taken it anywhere with a real grade. We'd like ...

^ Yes, the 6 speeds in those 1/2 ton Chevys do a decent job in tow haul. Good on the upshifts, but they slam too low of gears too abruptly on the downhill. To the point that I only leave mine in auto mode towing downhill if I forget to go to manual.
I suspect that's what tore apart my trans, as I didn't use manual and basically abused the trans hard for the first 40-50k miles.
Different than jimlins experience, the programming will jam mine down very abruptly to 4000-4500 rpms in the right conditions, which in itself isn't bad, but the manner in which it does it feels like a locked downshift. IMO, the Rams and Fords have better tow haul programming.
If I was trying to preserve my own personal truck, I'd 100% run manual mode towing in the mountains.
By way of comparison, the 2019 GM 8 speed trans behind the 5.3 is improved for shift programming, IMO.
