Transmission Temperature

[superman07]

Just ignore this guy Sir. Every thread on transmission temp, limp mode, etc, he must jump in and tell us all how well his tech pack performs.

He posted into my thread and offered absolutely nothing. Didn't answer my question, didn't offer anything except some version of the same thing he has already said a dozen times.

All of our transmissions go over 195 with the possible exception for when we drive for 10 minutes to get groceries.

I can't figure out if this is a troll or he just forgets he has already told us how well his tech pack performs or if he married Henry Fords great granddaughter.

I think the issue is that Dave is using a third party external guage, not actually reading the correct sensor. The one that matters is the one plugged into the cars ecu, that effects limp mode operation. Anything else is poppycock.

Thanks for chiming in Sir.

What sensor would you recommend and where would I plug it in to monitor this myself?

I'm guessing Ngauge is the way to go since it connects to the OBD. pretty expensive, but the only way to know temps for base owners.

Wouldn't a $20 OBD2 bluetooth adapter + phone app work?

Has anyone tried monitoring the temps that way?

Where do I install one of these on our cars? I will look for one today. These are slick!

Don't waste your time, there aren't any inexpensive plug-in or Bluetooth OBD2 scanners that I have found that will report the transmission temperatures. I have tried about 4 different units with no good results. I talked to the engineers at Lemur Automotive in Canada that make the Bluedriver unit last week, they don't know of any that will convert that data. It looks like the N-Gauge is the least expensive unit identified so far that will show the transmission temps.
That is why I tried a stand alone gauge for the transmission and the differential. The biggest hurdle with the trans is where to mount the sensor. For the transmission I machined a port opposite the factory location. The differential was easier, the factory port is already available on the housing for the Tech Pack cars.
My intention was to report off-track conditions, since I have only run my car on an autocross track. The trans never goes beyond 130 degrees during an autocross session. One hour of highway driving 70-80 MPH in 90+ ambient air produces transmission temperatures up to 190 degrees and differential temps to 160 degrees.
I am planning to connect an N-Gauge to confirm the consistency of the transmission readings I get with the add-on gauge. I do trust the gauge, the issue for accuracy is where to mount the sensor.

You would just plug it into yiur obd2 port like a regular scanner, and pair it to a phone app(torque pro seems the most popular)

Interesting.

Thanks for the heads up.

I was just reading about the Inova Quicklink. Looks like it might report trans temps. $130 CDN. If it doesn't ill return it

You know where it is hiding?

Nevermind - I googled it.

Best bet for doing this on a budget will be OBDLink MX bluetooth dongle. This supports most vehicles 96 and up plus advanced Ford & GM vehicle networks (MS-CAN and SW-CAN) You will need this support for a lot of Ford systems/PID's. This comes with their app and works very well but I recommend FORSCAN for Ford vehicles (APP is in the Google Play Store for like $5). I use it on my GT and works very well. If anything cost effective will work for you guys it will be this combo

Will this system report transmission temperatures?
That is the primary reason we are looking at OBD2 connections.
The GT's don't have temperature sensors in the transmissions.

I cannot confirm since I have a GT but IF something will work it will be that setup at a very affordable price point. It offered the most information out of all apps I have used. Including the paid version of Torque Pro. If any one is in the Richmond VA area and wants to try it out you are more than welcome to meet up with me and test it before you invest in one. I don't personally know anyone with a GT350 to ask.

Here is a link to the supported modules Both the Transmission Range Control Module (TRCM) and, Transmission Control Module (TCM) are listed. i imagine temp is read by one of them. And if they are on the FORD MS CAN bus then you would need a compatible reader that specifically will read that bus to see any of the info. The OBDLink MX does.

I read somewhere on this forum or another can't remember, but there is a way to get the Transmission Fluid Temp using OBD2 blue tooth device and the Torque Pro Phone app.

Here's the details, is working for me...

Transmission Temperature wasn't installed in Torque, had to add it as a custom PID.

Add a custom PID in Torque by going to the "Settings" section off the main screen.
Enter the following for the fields it prompts you for:
"OBD2 Mode and PID" = 221E1C
"Long Name" = Trans Temp
"Short Name" = Trans T
"Minimum Value" = -40
"Maximum Value" = 260
"Scale Factor" = 1
"Unit Type" = deg
"Equation" = (((signed(A)*256)+B)*(9/8)+320)/10
Leave the OBD Header blank

Hit "Test" and make sure you get a value back. Then click "OK".

Next go to a screen where you actually want the gauge (Under Realtime information off the main screen).
Long press and "add display"...then pick a type of display...then select the "Trans Temp" (or whatever you
called the Long Name above).

You might have to play with the Min/Max values, as in my case the values were reported back in Celsius...See attached image...

Hope this helps

Thing I bought doesn't work and will be returning.
