PCM read trans and engine oil temp?

If the PCM reads transmission temperature, where is the sensor located?

Does the PCM also read engine oil temperature?

If I remember correctly from rebuilding my last 4L, its in the pan, just onder the filter. Dont quote me, that was almost 6 months ago. I think its basically a resistor thats chilling in the fluid.

The temp sensor for the tranny is on the valve body, i think. As far as i know only corvettes came with oil temp sensors.

Then with the temperature sensor in the pan at the valve body, the fluid leaving the converter could be at a significantly higher temperature.

Has anyone ever checked the temperature at the inlet to the cooler?

Don't the Denali's have a temp sensor on the dash...lower left if I remember correctly. I am told the Yukon came with the wiring but not the guage..never looked to confirm it.

Yea the Denali's have the temp guage in the lower left of the instrument cluster (also has a 120mph speedo)
