I use manual mode when towing our camper as well (especially in the Colorado mountains)......but I've yet to find a use for the "1" mode, which holds the transmission in first gear. How about you?
Grade braking control.

If you're going down a steep hill while towing, put it into that "1" position.

The truck will work it's hardest to hold whatever speed you were at when you selected that position. Expect for some high engine revs[emoji6]

But it truly works brilliantly

I've used manual mode for grade braking quite a bit. Been down plenty of high altitude passes at 5k RPM, with my camper trying to shove me off the mountain, haha. It works great, but I've seldom had to keep it in M1 because first gear is so low. I still don't understand the purpose of forcing it to hold 1st gear only. Why not just use M1, and tap the shifter button when needed?

That's just it, it doesn't go to first gear, the truck will do what it needs to to hold the speed you're at once you put it into that "1" position. It'll drop gears as it feels necessary from the current gear you were in, to hold your speed

Hmmmm.....that's interesting. I didn't know it behaved like that. I figured it would just slam into first gear and stay there until you shifted it yourself. I guess I need to play around with it more.

Yeah [emoji16]

Now, if you put it there from a stop, ya... it won't want to shift up [emoji6]

Hey MAKKAT did you ever figure out the second 1, if not, It is your current gear as your driving while in Manual mode. If you select gear M4 while going 0 miles the transmission is in 1st gear and will show 1, as you drive to 40 mph for example and the trans shifts through the gears to 4th it shows what gear your currently where that 1 your asking about is........

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
