We have had a few customers ask us how to use our OBD-AUS tool to bring up a transmission temperature gauge on their phones. This has mainly been for customers who have towing caravans. Even though they have an over-temp sensor and their dash light turns on, by the time the alarm, shows the damage may already be done.

An Example

We will do this example for a Ford Ranger, but the process is the same for any vehicle. The only difference will be the PID you need to bring the data up on your phone.

1st Step:

Buy one of our OBD-AUS units here for $39. This will allow you to connect your phone to your vehicle easily. All you need to do is find the OBD2 port which will be within 50cm of the steering wheel and you can access it using no tools. It looks like a rectangle plug with 16 pins and slope sides.

2nd Step:

Download the App onto your phone (for this example we will use OBD Fusion). This is a paid app, and will cost you $15. For the extra PIDS, it will cost you another $13. You are still looking at under $50 to have all this data at your fingertips and save you a costly replacement or trip to the mechanic. Note that this app is for example purposes only and you may need to use a different app for different vehicles.

3rd Step:

Turn on your Bluetooth or and search for the device called OBD AUS. Pair with this device; the password is 1234. You are now connected.

4th Step:

Open up the OBD Fusion App on your phone and you will see that we connect you to your car and you can see all the standard data. However, you will not have the extra custom data like the transmission temperatures. For this, you need to watch the below video.

You have watched the video and added the extra sensors for your car and now you build your custom dashboard with all the information you want to view.

All done! You know have a live feed to your Transmission Temperature and you can even setup alerts if the temperature goes up so that it beeps and warns you.

And for those of you with a Ford Ranger, here are the PIDS below for the Transmission that should work if your vehicle model is the year 2012 onwards. You will need to enter these into the custom PID part of the app you are using.

PID: 221e1c
Long Name: TFT – Or whatever you want
Short Name: TFT – Or whatever you want
Min Value: 0.0
Max Value: 200.0
Scale: x1
Unit type: ºF – Important
Equation: ((A*256)+B)/8
Header: 7E1


That will show in Fahrenheit.Now the really important part is in Settings/Units make sure Use Celsius instead of Fahrenheit.

Note that this is a guide only on how to add the transmission temperature gauge/PID to any app. Due to the numerous variable PIDs available for transmission temperature, OBD2 Australia does not provide these PIDs. You can find transmission temperature PIDs for your vehicle through an online search. OBD2 Australia does not refund paid app purchases. As this is a general guide on how to add PIDs, and the video is third-party (and additionally PID coding is optional and beyond our scope), we regret to inform you that we will not support any concerns or questions regarding this.
