7MT dash display alert
Can someone with the M7 help me here?...I very occasionally get a message on the screen that starts out "Manual Transmission...." But it is displayed for such a short time, 3 seconds or less, that it disappears before I notice it and can read any more than the first line. I don't know if it is indicating a temperature issue, traction issues, clutch problem, dissatisfaction with the fact that manual transmissions are not to be included on the C8, or what. And most of the time (maybe 5 total in 2,500 miles driving) it appears when I'm stopped.
Is there any GM documentation that lists ALL the messages that can be displayed on the center screen?

It might be the "Shift to fourth" message? Are you winding up through first with fairly light throttle? I am usually heavier on the throttle in first, so I see a message blip for a second about doing the skipshift thing, but it goes away almost immediately because I'm fairly leadfooted.

It also says something like "shift denied". And yes depending on how much throttle you apply the message might go away very quickly.Next time see if your going from 1st into 2nd, that is the only time it will appear.
If there aren't any stored codes I wouldn't be too worried. If it was a real serious problem the check engine light would remain on.

Yeah I'm thinking you're seeing the 1-4 message. That fits. The easiest way to never see it again is to rev to 3000 before you shift 1 to 2. Everybody, including car, will be happier. Freaked me out the first coupla times it happened to me. What the hell happened to my torque??? But it was just a matter of learning the M7. Never happens to me any more--except this one stupid short round-about I hate SO much!

"...it appears when I'm stopped." It is not going to be "skip-shift" when he's stopped. 
I HOPE!
4700 miles on my C7 St'ray and have never seen it or any other message, ever.
Now, on my C5 when still quite new, I got a flash of a message a couple times about who knows what when setting still. The dealer just happened to see it, too--once--but it never ever showed long enough for anyone to actually read it, and they had no clue--no codes set. In the intervening 17+ years I've never seen it again. But, maybe the next time I start the ol' sled, who knows?
As noted, if yours doesn't set a code the odds of anyone being able to do anything with it until something falls off are slim to zero. Drive on and see what happens... if anything.

The fact that there is even a thing as a 1--> 4 shift thingy blows my mind. I just drive ride first gear > 20 mph then it goes away. then shift into 2nd. I feel like 1 --> 4 would lug the engine, not sure how that provides better " fuel economy" ... who the hell buys a vette and cares about fuel?

Never seen such a thing at start-up or with the vehicle running and stopped either. Also, in my 2014 owners manual, Instrument and Controls section, Vehicle Messages section, it lists all the messages you can get in the DIC, and this one you are receiving is not listed. So my thought is that if this is a newer car, there might be something new in the software that is giving this information and those of us with earlier models wouldn't have this feature, what ever that might be.

No, this is not the 1 -> 4 skip shift message...that does occur under light acceleration, warm engine, etc. This is a 2019 M7 Stingray, and the mystery message occurs with the clutch depressed and waiting to start moving. No tone to alert you to look. It has happened a couple times just prior to releasing the clutch in first gear after holding it down for 30 seconds or so (As in waiting for a traffic light to change green. Can you believe that...somebody actually NOT looking at their cell phone at a red light!)
All three times I've seen the message it disappears just after I read "Manual transmission blah, blah, blah...."
