OBD Tranny temp sensors help

I just bought the OBDlink mx for my 2015 TRD OR. I finally found the Tranny temps in the app, but they are labeled as :

A/T oil temperature 1
A/T oil temperature 2
A/T oil temperature 3

How do I know the difference between these ? Is one for the pan, and one for just the overall temp of the tranny ?

Id really appreciate any help on this.

About to do a drain and refill on the tranny oil and want to be able to look at the temps. Thanks

 

There's only 2 sensors, not sure why it's showing 3.

One is Torque Converter temp and the other is Pan temp.

The one the rises faster should be converter temp.

Your looking for a 95-115F pan temp to check the fluid.
