Help with transmission temperature on Torque Pro

[jonathannickel]

I installed a bluetooth OBD2 reader in my 2001 EVC to monitor transmission temperature using Torque Pro on a Nexus 7 tablet. Torque Pro is up and running and works great for everything except transmission fluid temperature.
I installed the gauges on the Torque Pro screen for both "Method 1" and "Method 2" transmission fluid temperatures but get no numerical display.
If anyone has gotten this to work, a little help would be appreciated.

The OBD2 reader I got for my Eurovan shows two sets of code. One for engine, one for transmission. You have to toggle between the two. When you toggle to transmission, it reveals transmission temps as CLNT TMP.
So in short, look for tranny coolant temp reading. Not transmission temp reading. Maybe that helps?

Actually, you just need to turn off the bluetooth device and back on again after about 10 seconds of having the van on. Not sure why this is the case, but it works for a few of us. Some have even installed OBDII cables with a switch to make this easier.

OK, I bought a bluetooth OBD2 reader with an on/off switch and downloaded Torque Pro. Everything seems to work except the transmission fluid temp. I have toggled the OBD2 on/off after engine has been running a while and I am still having trouble reading the transmission fluid temp.

Is there a start up procedure that works for you?

I have a 2001 EVC.

thanks,

Just an update to let everyone know that Android 11 update has caused Torque Pro to stop functioning. Hopefully Torque will fix this bug soon.

I thought I would give my recent experience in case anyone is looking for help. This might be something to try.

I have an android head unit in my 2003. In addition to providing all my sound system options it also allows the installation of android apps. So of course I installed Torque Pro, version 1.8.205 to be exact. This version has sensor options of:
Transmission Temperature(Method 1)
Transmission Temperature(Method 2)

Method 1 has worked well for me for many years. Method 2 does not work. And yes, I have to cycle on/off the OBDII bluetooth dongle at times to get transmission temp.

Recently, I had the bright idea of repurposing an older Fire tablet to capture a number of Torque data points for longer trips. So, I downloaded the latest version of Torque Pro, version 1.12.101 and connected it up to the same OBDII bluetooth dongle. But now I discover Transmission Temperature(Method 1) is no longer available! Only Transmission Temperature(Method 2) which does not work. After doing some reading on the Torque forums and other recesses of the internet I went back to my Fire and noticed that Torque recognizes 2 ECUs. So I guessed the second ECU is actually the TCU and the 'engine coolant' is actually transmission fluid temperature. Fortunately for me, I also have VCDS so I could verify the temperature readings and it is in fact the transmission fluid temp. The Torque sensor name is ECU( 18 ): Engine Coolant Temperature.

Hopefully someone finds this useful. YMMV.

Thanks, that is fantastically helpful!

I recall being similarly confused using Torque Pro on my 2002. Whatever reading I was getting off the program didn't correlate to the analog temp gauge I had hard wired to the transmission. So I wasn't sure which reading was correct.

I'll have to look at what ECU 18 is showing now. Wish I had figured this out, when I was changing my transmission fluid and realized all my temp readings were off. Thank god I must have been close enough, as the transmission hasn't blown up yet. Fingers crossed.

I'm using a used scangaugeII that I picked up on eBay, but it had old firmware and I had to update it...

I also have a handheld Autel unit. Just confirming that my Autel also saw "two ECUs" as your bluetooth adapter + Torque Pro did, and the 2nd CPU is likely the TCU and has a temperature parameter that seems to be the transmission temp.
