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...

My 2001 3500 8.1 gas would downshift when towing quicker than I wanted it to do but that did keep the speed up. With the 05 duramax It wants to stay in the gears longer than what I feel is ok so I hit the button to go out of overdrive and let the engine run free. I think your truck is doing the same.
