The THM 375/400/475/425 Troubleshooting Guide by GM states a normal operating temperature of 170F.
http://www.bdub.net/manuals/THM_425_Trouble_Shooting.pdf

Other transmission related websites say an "Ideal" operating temperature is 175F....

Good to know - thanks for posting.

Trans temp sensors are typically located in the pan or valve body.

Both the Ragusa and Rockwell pans have ports for temp sensors. My pan is Rockwell with a 300F VDO temp sender.
IIRC the Digipanel uses a thermistor strapped to one of the trans cooler lines. Most likely calibrated for temps at that location. It would be nice to also know the fluid temp as it exits the transmission.
