Before anyone flames me, I looked through entire owners manual and my dealer cant even figure it out as they looked as well.

 

I traded in my 2012 1500 for a 2012 2500hd that was a left over. zero miles on it!

 

anyways, in park, drive, or manual, there is always a 1 on the far right (see pics)

 

as you can see when your in manual there it shows M1 1. So it has nothing to do with that.

 

any idea on what it is?

Is that the indicator to tell you what gear you're in? Take it out for a drive in manual mode and shift up; it should change to as you upshift. And I think that's a colon between the "M" and the "1". The "1" doesn't show up on my 2010 when it's in "D" mode, so I don't know what's up with that.

The "1" is there if you want to run in 1st gear without a shift and the "M" is there if you need to shift yourself up or down with the thumb rocker button and where the "1" is that will show you what gear your in when shifting manually.

Can you put the shifter 1 position lower than M? Maybe it's just another selection to let you lock it in 1st

It's 1st gear, just takes the transmission control module and solenoids out of the loop by putting the manual shift valve into the 1st gear range.

you can pull it down past m into just first, it will just stay in first gear.

All explained in your Owners Manual. Read it.

I pulled out the manual and read what the 1 is for.......

 

The answer is something I did not expect.

I glad i read it finally and know what it is for !!!!! Tranny Brake..................

Down steep grades and let the tranny do all the work, I have the 6 speed.(same as the allison) as it says in the manual that I READ !! lol

It works like the Allison tranny I should of said

ok guys, I looked over that owners manual, and so did the dealer and they didnt know (not a shocker) but if someone can tell me what page it is on so i can review that would be great?

 

and txab, the entire point of a forum is for someone that has the knowledge to pass it along to someone who doesnt, i couldnt find it in the book, so thanks for that pointless response.

Yep, just a quick short cut to first gear.

Instead of having 6 5 4 3 2 1 you have D M 1, less clutter and fuss.

I like it.

Damn man I just told you what it is, so I'll do it again in a little more detail, The 1 is there if you want to hold it in first gear and when you put it in manual or the "M" the blank spot in-between the 1 and "M" will show you what gear your in when shifting in manual mode. So in your 2nd post in your picture your truck is in manual mode as seen by the line under both the "M" and the gear your in so take the thumb shifter and toggle up you will see the 1 change to a 2 and so on and when you toggle down it will drop down.

      2 speed transfer case optional now?

      I thought I was building a HD 3500 srw, maybe I was lost.

      Which 2027 engine will you choose?

      By Coastie05 · Posted

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.

      It’s never dry here but it gets hot. My 4 vehicles I keep at home drive an 18 mile loop. One 6 days a week. Two about 3 days each and one once a month. Only one goes on trips about 4 times a year 1000 to 2000 miles each time. One 26 years old gets driven once a month for 22 years. One 14 years old goes 6 days a week. The other two are recent at 2 and 4 years. All are performing normal no extra service other than that would be half of recommended or severe service in the maintenance manual. No extra water or steam out the exhaust or premature plug wear. I would consider an 18 mile loop would be enough. So apparently once a month at 18 miles for 22 years has kept the collector car running well. About 45 minutes a month.

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.
