Just installed my Trans Temp Gauge , went for a drive and the gauge slowly climbed to 245 degrees. I installed the sender unit of the gauge to the test port of my 4L60E. I know its not the best spot but its temporary until I buy a trans cooler. Trans has 9,000 miles, is stock except for the average tune (torque reduction, base pressure, ect.)
Should I be seeing the temp that high? It's raining now so I'm done for the night. Any ideas or suggestions?

245 is a very high temp for any trans. Thats why a Trans cooler is a must on all transmissions regardless if it has a stock or aftermarket stall. Mine used to get to 230's when it was all stock and when it started to slip it would peg 250's. After the adition of a cooler the temps droped to around 210's. Now with a lower temp thermostat in the car lower fan on/off settings, and a built trans I see 200 tops sitting traffic on a 90 deg day.

If it's accurate, that seems very high. Mine sits around 175-180 on the highway, and 190-210 in the city (I try to avoid stopping if I can help it )

Using the presure port can be deceiving on the actual trans fluild temp , Your mostly measuring the transmissions case temperature there ,I would move it to the pan then decide if its too hot.

Thanks everyone. I bought a trans cooler, and will pipe the sensor there.
I was hoping my trans wasn't that hot, but it makes sense that the sender is sensing the transmission casing rather than the fluid.

Yes and with the exhaust and all nearby the reading may be erronious
