I look at it this way, from what I found out normal operating temp for the trans is between 160 and 220. If the sensor is in the pan you know that your trans cooler is doing it's job when the temp is in the normal operating range. I like knowing the temp of the fluid going back to the trans is within range.
If you move your sensor for the cooling fan somewhere else then the auxiliary fan isn't going to do it's job like it's supposed to.
When I did my test I was within 50 degrees.
