2017 GMC 6.0 Vortec - Manual Shifting?
I notice when I am towing my RV, my truck seems to try and down shift sometimes when climbing a hill before it should. Do any of you guys manually shift to get more power or save gas in these situalt...

I've tried to use Manual mode to manually shift up through the gears... and it doesn't work well. It's not like the "flappy paddle" shifters on performance cars. The reaction is severely delayed.
Yes very true, was never designed for that application. The advantage in using it is primary locking out gears that you can't or don't want to use while towing, and of course quick downshift. It works much better in my opinion then letting the computer shift for u on tough grades. Seems like GM will let the engine almost bog down before the up shift sometimes. Watch the TFL test u will see what I mean. So they gave us that easy quick way of keeping the truck in its powerband. Like I said before, I will drop a gear prior a hill sometimes just to keep speed. It only jumps up a few rpm but keeps it in the power band when I most need it. Won't harm a thing, no different then downshifting a manual tranny.
