OBDII Reader for Trans Temp

Yeah, I did a search for the a/T and auto and temp and trans and I’m not finding it. I have a 2015 and that’s the package that I downloaded but it is not showing automatic transmission temp anywhere. Maybe it doesn’t work in that year? Does anybody else have that year and they can find the temp thing?

 

I'll have to add the "Voltage Load" to my OBD Fusion dashboard! Didn't even realize it was available. What is the difference on your dashboard between "Voltage Load" and "Volt Load"? Looks like they are reading different values.

 

Ok finally got it working. I used the thread below and those values made it work. Quoting the main part.

You create a new PID by following the steps below.

Settings
User-Defined PIDs
Menu
New

Enter the following into these fields:
Name = Transmission Fluid Temperature 1
Description = Trans 1
English units = F
Min value = 0
Max value = 300
Metric to English scale factor = 1
Module/Header = ECM
OBD Mode = 21
PID Number = 82
Equation = ((((A*256)+B)*(7/100)-400)/10)

I managed to piggyback what Firefly did and was able to get both pan and torque converter temps. For the torque converter temps, keep everything the same except the formula. Change A to C and B to D.
Equation = ((((B*256)+D)*(7/100)-400)/10)

I bought a $20 bluetooth OBDII reader on Amazon (

for Android Phones ONLY - Wireless Bluetooth Diagnostic OBD2 Scanner Car Code Reader and Scan Tool for All 1996 & Newer Vehicles ELM327 Compatible OBDII

https://www.amazon.com/gp/product/B005NLQAHS?ie=UTF8) and use the free android app Car Scanner. Worked great to monitor trans temp while towing.

 

Dang this isn’t available, does anyone else have any other suggestions? As far as I can tell you buy a OBDII reader doesn’t have to be great quality and then you download an app and you can monitor your trans temps ect, I’m most interested in the fact that if it’s accurate I could change the trans oil off if it.

 

I use the basic Carista OBD2 bluetooth reader Only paid for one month of the Carista app, so I could change some settings (turn off seatbelt chime, adjust number of blinks for quick turn-signal). I use the OBD Fusion app on my iPhone and built a dashboard to monitor all my stuff, especially transmission temps and TC status during towing. Works fine. I think most any brand bluetooth reader should work.

Looks like Carista also has a newer more expensive OBD reader available now ("EVO"). Says it's faster, but I don't really notice much communication lag with my current setup.
