I recently purchased a BAFX OBDII bluetooth adapter and got Torque Pro going on my Android phone. Everything is working great, and once I loaded the Ford specific OBD PIDs, I was able to get transmission fluid temperature readings in the app - awesome!
However I'm wondering at what location is the temperature measured? Is it polling fluid temperature within the pan, or at the cooling lines?
Additionally I see that there are a handful of DTCs associated with the 4R55E transmission temp sensor. I don't mean that I have these DTCs - I just see that they exist in a list of possible DTCs.
What does the ECU do with this information? Does the trans temp affect how it shifts the trans?
Frankly it really surprises me that if this reading is available to the ECU, it isn't something that is included in the gauge cluster - at the very least as a warning lamp if the trans is overheating. Typical bean counter stuff I bet.
