I'm using an OBDLink LX OBD adapter and the Torque app. The app has 3 monitors for transmission temp, but I don't think they are correct. One does nothing and the other two mirror the coolant temp reading. Does anyone know the PID Volvo uses for transmission fluid temp, or is it even possible to measure it without using VIDA/DICE? I'm hoping there is a somewhat easy way to do this, but my gut tells me there isn't.
Transmission Fluid Temperature

I think you might be talking about the manifold air pressure sensor (MAP).
Automatic transmission temperature is correctly displayed in "Car Scanner ELM OBD2" for Android and iPhone.
Pretty cool, has plenty Volvo-specific PIDs:
- engine oil temperature,
- coolant temperature,
- AT fluid temp,
- catalyst temp,
- MAF rate g/sec,
- battery SoC and charging current,
- AT gear and torque,
- DPF soot (g) and DPF temperature (diesel)
- Aircon pressure and front cooling fan speed
Works best in 2008-2014 Volvos. There are two profiles: Volvo OBD2, and Volvo 2010+

Thanks for this, great to have an accurate reading!!
Does it pull boost pressure as well? My ScanGauge II too does not pull boost pressure readings on my S60. My old P1 S40 it pulled boost pressure reads from, but not my S60 for some reason.

Sorry for the -very- late reply on this one but I am looking to get transmission temperature reading working on a 2005 XC90 with a V8 engine.
The above settings did not work. Does anyone have the correct PID for my car?
You will get it in Car Scanner Elm Obd2. No pids required, just choose Volvo Platform 2 29-bit profile.

Tried that and works! Now to find a way to keep that app active while driving longer stretches: at this point the screen shuts down at the general Android phone screen timeout.
Thanks so far 🙃
Any info on what the safe temperature range is for the transmission?

The currently visible app permissions suggest that the app has permission to keep the phone from entering sleep mode. I have contacted the developer to see how to progress from here
Just wanted to confirm this setup worked on our 2011 XC70 T6, though I used OBDLink app instead of Torque.
What transmission temps are people seeing with hard use (towing, track days, etc)?
