so I know this is an old thread. I want to install a transmission temp gauge in my Yukon since I tow cars. I have a 2006 Yukon SLT. Anyone know what I need to do in order to get the transmission temp?
The temp sensor and wiring are already there. They don't include the gauge in the cluster though.
If you get the Escalade cluster conversion, it comes standard with the trans temp gauge along with all of the other upgrades.
That's what I did.
