Measure both on your Torque Pro application. Also measure your coolant temperature off the head. All of these are important. You should find out what model transmission you have also... is it a C6, or something different? Take it to a transmission shop and have your ATF changed, and ask them what temp the max operating fluid should be kept at.
You can also set alarms on your Torque Pro App for maximum temperatures, and then the gauge starts blinking, although I'd prefer an audible sound instead for a gauge whose temp is running too hot.
If it sounded off, look down and see which gauge is blinking.
