Did you notice if the AT Temp tracked right with the coolant temp for an extended period of time? Did the AT Temp only rise when above that level when you put stress on the tranny?I pulled my my boat and trailer (~1000 lbs) over pass this morning. I pushed her hard in the 75MPH range on some steep grades. Peak AT temp got up to around 208F (~97.77C). It normally ran in the 190s and about a 15 degree spread between the coolant and AT fluid as things heated up. That temp is still fine with this synthetic AT fluid.
I have an OBDLink LX bluetooth and TorquePro.Mine is always a few degrees apart when there isn't a load and then noticeably rose during heavy load. It's obvious on mine there are different sensors being polled.
IMO: If you are seeing 100% sync with coolant you are not likely reading the AT temp probe but coolant.
What software/hardware are you using?
I was using OBDLink today with their OBD adapter.
I was going to post a graph but I still had the log area setup to capture AT data for my GX 460. Maybe next time.
Another example during recent AT fluid swaps.. coolant warms up far faster than the AT. AT temp will be too cold still if you are using coolant as 122F temp indicator.
Thanks for that.I haven't used Torque in a while.
You might want to test out the free OBDLink that comes with OBDLinkMX+ and loaded up the free Mazda add-ons within the app.
Android - OBD Link
IOS - OBD Link
"Transmission Fluid Temperature" will show up under: Network A ---> Transmission Control Module
I need to play around and see if the "Torque Converter Lockup State" will display. It does on my other vehicles.
I installed the OBD app without any problems. I looked at "Extras" and see that they don't have PIDs for the 2019 Mazdas yet. I gotta call Customer Service and see when they anticipate a release date. The standard SAE PIDs don't have oil temp or tranny temp. Not sure what other Mazda measurements might be available in a specific PID set.
