Well, 550 miles of towing later, I think she’s broke in
.
Few things I’ll say about the 10 speed. It will shift a lot if I’m cruise control and hauling heavy. You honestly never feel it shift but it will bounce back and forth from 10th to 7th on hilly terrain. It will also skip downshifts I found, that or its real quick downshifting through the gears. I was in 9th gear at the bottom of a hill and hit a real steep grade. It seemed like it went straight to 7th and I watched it jump from 1600rpm right to 2400rpm. Did it 2 or 3 times but I never tried to make it do it myself and you can’t watch gear selection to know what it’s doing.
I wish gm wouldn’t make cruise control so touchy at speed to downshift when hauling heavy. I’d rather see the truck drop 2 mph while it try’s to stay in gear but I guess it’s a fine line on that. Probably just need to get use to it.
1-2 and 2-3 up shifts in tow/haul are harsh (like big defuel type shifting, not tie up style) over 50% throttle up to about 80% throttle. I’ll see if it learns out of it. Has maybe 10-15 shifts through those gears.
It takes some getting use to on make it use its torque. It’s not like the 6 speeds where you could kinda lay in the throttle and it would power through. It wants to kick down pretty easy but you can kinda figure out the throttle after a bit of driving to use the torque.
When you put it in “L” from “D” while in tow/haul, it puts you in the lowest gear/highest rpm at or under 3200rpm instead of just going to the current gear. That’s annoying when you want to do manual downshifts down a hill or hold a lower gear for pulling hills. The grade braking is awesome but I found myself going in and out of it on a windy 7% grade because I’d slow too much and have to give it throttle. If I shifted it myself, I’d never have to hit the brakes. Sum bitch will rev to 4200rpm and damn near put you through the windshield.
The benefits of the 10 speed far outweighs the little quirks I noticed though. It keeps this sucker right in the power band on hills. First gear really gets the load moving easy from a dead stop. It seems to play real well with the power.
I feel like it’s picked up some power as well. It was pulling hills better on the way back than Monday. The camera views are awesome. You turn the blinker on in tow/haul and it shows a side view of the truck/trailer on the deck in your typical blind spot. The truck stays cold too. I only heard the fan one time and it wasn’t even when I had pulled a big grade. Stayed around 180ish most the time and hit 210 once. Trans never went over 178*. The onboard trailer features are nice too!

The leg room back there is ridiculous
