Hey everyone, new Sierra owner here, just picked up a few days ago with 9k miles on it. One thing I noticed right away was that I was missing where the gear indicator is on the display (not the number/speed, but the actual PRNDL). I figured that it was buried somewhere in the settings, so I have not worried too much about it. I took a few minutes yesterday to dive into the display options and found nothing relating to gear. My understanding is that the letter should be displayed below the truck image on the right side of the cluster, but mine is completely blank. I also tried the factory display reset button in the display menu with no luck.

 

I have searched around a little bit, and as far as I can tell this seems to be a new issue? The only things I can find related to this are looking to display the gear speed throughout shifts. Has anyone heard of this issue, any fixes I am missing before I bring it to the dealer? Or am I just being dense and completely overlooking a setting? I figure if it was something serious, like the shift sensor on the transmission, I would be running into much more serious issues. It runs, drives, and shift great. No problems that I can tell. It has the LZ0 powertrain if that is important. Thanks!

As far as I am aware, the "traditional" PRNDL does not appear on the dash display. But it does, kinda, on the consol shifter. The only thing that appears on the dash is the currently selected range; P, R, N, D, L. As far as I know the dash display also doesn't show which forward gear is engaged at any particular moment.

 

I think I read somewhere there may be an aftermarket device that will display which forward gear is engaged as the transmission shifts through them.

Hey Dan, thanks for the comment. Sorry, maybe I shouldn't have used the word dash. I mean the PRNDL indicator is missing from the gauge cluster above the steering wheel. It looks like it is normally under the truck image. Mine is completely blank in that area.

No worries, Matthew, I understood what you meant, but I probably should have also used gauge cluster. While your cluster is ever so slightly different than mine the "gear" selection letter is in the same place. As you've seen the P will change to R, N, D, or L depending on what you do with the shifter. The full string of "PRNDL" doesn't appear at all, ever, as far as I am aware.

 

If you do select L with the shifter a number will appear next to the L, and that number will indicate the highest gear the transmission will shift up to. In other words, with the engine running and truck at a dead stop, if you select L with the consol shifter the letter L will appear on the dash cluster, and the number "1" will appear next to it. If you start driving the trans will stay in 1st gear until you toggle the right side paddle behind the wheel. Toggle the paddle once and it will shift to 2nd gear but not past it. Same for the rest. If you select L while at a stop, then toggle the right paddle until the number next to the L reads, say, "7", and then start driving the trans will start in 1st as normal and automatically shift up to, but not past, 7th. The number next to L never changes from what was selected.

Dan,

 

Should have clarified, the image I posted was taken off of google. The letter shown, or the PRNDL, is what I would expect to see like in the google image. My truck has nothing shown at all, not the single letter or the series of PRNDL. Its just blank space. I will post a picture in a few minutes.

Ah, evidently my reading comprehension isn't so hot today. Now I understand whatcha mean.

 

Will be interesting to see what your cluster display looks like.

Here is a photo of mine. This is what it looks like in every gear, nothing shows during gear selection either.

Sounds like a possible software programming issue.  I'd take it in and see what they can do as the PRNDL is a requirement for all vehicles built and it has to work.

If I were you I would disconnect the battery for about 10 or 15 minutes then reconnect to let the system reboot and see if it comes back, might save you a trip to the dealer if not then a trip to the dealer as newdude said.

There are 4 'themes' for the display.

On mine, 3 of them display the gear in the location show in the pic 'from google'.

The 4th theme displays the gear in the bottom row, instead of the rhs display. 

 

 

As a diagnostic, check all four themes and see if it shows in any of them.

I'm with redwngr on this.  Try adjusting your screen options.  The first image you posted from Google shows the truck is in Sport mode and has a different tachometer than what you posted in the 2nd pic, which shows the truck is in Normal mode.  If that doesn't work, try disconnecting the battery for 10-15 minutes.  If the battery truck doesn't work, take it to the dealer.

I did briefly run through the theme options, it looks like the “clean” option is supposed to move it down to the bottom section, but no luck. There is just a blank area where it’s supposed to be. Also did the battery disconnect for 30 mins, nothing. I’ll call the dealer tomorrow and keep y’all posted. Thanks for the ideas on this.

    • Thanks JR that would be great if you could do that !!! Do you have a link to where this was discussed before ? I cant seem to find it  Thank You Again !
    • Oil pump noise was discussed before.  I will try to remember to record a remote start later this morning. 
    • There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
    • On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.
    • 2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!
