I searched around the web and found that there is not a trans temp display for my 2008 Tahoe Z-71 except by connecting a scanner to the diagnostic port. Is that true? I have seen some trans temp displays on the oem dash on the same platform year 07-14. Thanks in advance.

A live data scanner will have that reading. Typically it takes a 3/4 ton or larger platform for it to display on the dash cluster. I sent my dash cluster to Digital Dash Display and got a cluster with a transmission temp gauge on my 2005 Tahoe Z71.

should be able to pull it up in the dic display I have it on mine and many others do as well, just cycle thru pushing the top button, it should cycle thru miles, mpg, etc, just go until you see trans temp.

Thanks everyone. I’ll try it today and see if I can find it. I had always thought it was somewhere in there.

So, I tried scrolling through the DIC and nothing would display. Hmm? I pressed and held it several times and still nothing. Anyone one run into this issue where nothing would display? I do have a Range AFM disabler. Not really knowing if that made a difference so I tried it with it plug in and with it removed. Same result.
Anyone have this happen before?

nothing at all? it doesn't show mileage or anything?????? if so then the display is burnt out
and you do not "hold" it for the top button you just press it, the only thing that gets held is the "checkmark" button for things completely unrelated to transmission temp display

Also, just saw it may be a bad fuse or a switch. I’ll starting doing some diagnostics on it and let you all know.

Yep, nothing displayed. The switch is appears to be functional as it can be pressed in from that stand point.

I can read all the other display functions such as TPMS, engine hours, mileage, etc just nothing with the DIC. All the other buttons below the DIC work as they should.

That doesn't make any sense, the mileage is shown in the dic, when you press the top button it will change what is displayed so are you saying the top button does not cycle the display?

You should post a video of what you are doing, after you read your owner's manual. Do not shoot the parts cannon yet.
I will take short video and post it later today. I did read the manual after it was first mentioned. Once the display was shown to not cycle through it functions and the button appeared to be physically operable (meaning I could press it in and it would return to its original position) then I started the troubleshooting.
Seems like an odd situation but leaning towards maybe a bad switch. Maybe the previous owner loved pushing the button. lol.

the switch is pretty cheap, I think you just have to pull the shroud from around the cluster first then you can access the switch in any case it's a few screws only and relatively easy to do

It’s a relatively easy replacement. Just have to be patient and not crack the trim when removing. Lol

I tired to upload a video but it’s too big. Going to replace the switch and see if that fixes it.

Here are screenshots from the video of me pressing the different buttons showing the respective options on the instrument panel.

the trim piece is fairly flexible it shouldn't break unless you really try to pull it out farther than necessary, funny thing I just had one in my hands the other day at the junkyard but didn't grab it because it didn't look any better or worse then mine.
