TH 350 Tranny Temp Question

[PbFut]

I have little experience with TH350 transmissions. Using a Autometer electric temp gauge with the sensor inline on the OEM cooler line at the exit of the tranny, I am getting what to me seems rather high temps. In the 210 to 230 range. A check of the pan temp with a Temp gun it is at 175 to 180. Does this seem normal, or do I need to investigate further? Checking calibration of the Autometer sensor with a temp gun and the temp of the sensor seems to match the Autometer Gauge. The good news is that it shows the coolers doing their job. But 230 out of the case is a bit scarry to me. Air temp is 70, hate to think what 95 brings.
