Help with transmission temp OBD2

Post by unbrakeable »

Looking for some help in regards to picking up the trans temp from my ECU on a 2005 chevy 6.0 LS engine and 4L80e automatic transmission. So far from what I have found via google there isn't much out there for appropriate code to do this, though there are all kinds of PID's offered for various other gauges.

There is a company that makes a product called "Scan gauge" which is basically just an OBD2 gauge display and they advertise that it does infact pick up and display trans temp so there must be a way to do it. I wonder if there would be a way to find and use their PID?

Pic of my swap project for attention!

Thanks for the help!

Not sure if this would be helpful, but if you have the One+ B there is a sketch to do some CAN sniffing. I'm not really familiar with it but might help discover some data:
