First vehicle I've ever owned with a gauge for this. Like many of us, I'll be towing with my 2018, Z71, 4wd, crew cab, long box. I would like to be able to use trans temp data to stay out of trouble and in my comfort zone. But I've looked over both my owners manual, and diesel supplement and can find no guidelines on when to downshift, back off, or just pull over. Please point out guidance I'm overlooking and/or advise me on ROT's/guidelines you all use to operate safely and efficiently.
