I haven't used that method yet though.
If you use the Torque app, you need to add a custom PID to read ATF temp. The ATF temp PID that's already in the app does NOT work. It simply displays the engine coolant temp instead. You need the custom PID for the real ATF temp. Adding the custom PID is pretty easy. It consists of filling out some fields in the app with a bunch of computer programming gibberish. I found the info online that told me what to enter in each field.
When filling the transmission, it not only needs to be at the correct temperature, but the engine also has to be idling in park. If you fill it to the "correct" level with the engine off, it'll be about a quart too low.
I also have the Torque Pro App, can you please share how you were able to rear the AT temps?
Yes. I took some screenshots; you can see them below. Go to Settings, Manage Extra PIDs/Sensors, then Add Custom PID. Then add the info in the screenshots to the appropriate fields:
Thanks. I just ordered a bluetooth scanner and will download torque pro.
