02 excursion transmission temp
02 6.8 4x4 excursion. When I start the truck cold, the trans temp gauge immediately moves to "running" temp. Not really sure how this happens, I'd figure that if the xducer was trash it would ride all the way high or all the way low. Any ideas what's happening here? I'd sure like a functional gauge...

I do! I do! I don't know how I missed your post when you first put it here.
The "gauge" is an idiot light with four positions. Below 50F it reads cold. From 50F to 230F it reads right in the middle of the range. From 230F to 260F it reads yellow. Above 260F it reads red.
There is nothing to troubleshoot. It's working as designed.

The problem is in the programming for the instrument cluster, not the temp sender. The sender is sending real data to the PCM, the PCM sends the actual temperature to the cluster, and the cluster processes this data and outputs what you see on the gauge.

Is it bad that I want to try and get the tranny hot enough to move it into the yellow on purpose just to verify that its working? sounds insane when i say it out loud...
