Looking to get a digital gauge display to monitor eng/trans specifics that are not covered with the stock dash instrument cluster. I see EDGE makes one for the 6.0L in the 2012 Silverado, but not for the 2012 Express. What is the difference? Any other options out there for the 2012 Express with the 6.0L/6L90e?

 

Look into getting an old Android phone or new tablet and the Torque app. Along with an OBD2 adapter you can have just about any display you want.

I have this adapter but there are many othershttps://smile.amazon.com/gp/aw/d/B005NLQAHS/
I also got a short OBD2 cord with a 90° end to be able to tuck it out of the way.

 

Thanks for the links. Does the one you use have tranny temp?

 

It did transmission temp the first time I hooked it up. After my phone updated to Android 11 it stopped working and I haven't messed with it to get it working again. Other people have had luck with even some of the very cheap adapters.

 

I have the Scan Gage. It seems to provide more than enough info. However, I did have to have them create a custom configuration to monitor trans temp. If you go with one of those, I can send you the settings.
