The trans temp it reads comes from the TCM (the electronics module in the transmission), and *probably* an IR thermometer on the pan is a decent approximation, but don't quote me on that.
Thanks for the info. I was hoping a tuner could read the temps, I guess you replace the fill plug with thermostat and add a gauge, for people who track there cars.
