Yes, there is a temperature sensor internal to the transmission that I can read. In 2000 they change the sensor, but I have the voltage/temperature curves for each one. During setup it'll be calibrated in some manner so I know which one you have.

That said, I was planning to display the transmission temperature on the handheld screen. Outputting it to another gauge... might be possible, but probably not on the first or second revision.

The bare circuit boards should show up this week. My test vehicle is being delivered this week as well. Hopefully in a couple weeks I'll be to the point of testing control of the governor pressure solenoid. If that goes well, I'll have a lot more coding to do
