OBD II Scanner - Transmission Fluid Temp

Has anybody found a scanner that will read our transmission fluid temperatures properly? Ive done a good bit of searching and it doesnt seem as though anybody has cracked the code on the 5 spd trans. Ideally, I would like to get a Bluetooth scanner that I could move between vehicles but mostly Im interested in reading TFT for my 05 Tundra DC and 08 Sequoia (5.7).

Re: OBD II Scanner - Transmission Fluid Temp

Back in the day, I got the ATF temp to show on my Torque App reading a OBDII BT plug I got off Amazon. Now, these are dirt cheap.

Re: OBD II Scanner - Transmission Fluid Temp

Scangauge II, the best IMO. https://www.scangauge.com/ all you do is input the proper code for your truck and it will read the temp just fine. Best choice though just follow the link 2003bajatundra4x4ac suggested. Forgot to mention, make sure the unit you buy from scangauge has the latest firmware, buyt it directly from them and you won't have an issue at all, then input the code that's posted in their website and you are good to go.

Re: OBD II Scanner - Transmission Fluid Temp

Thanks everyone for replying. I actually have a ScanGuage. Ive tried all the codes I could find online. I even tried modifying some of the ones that have been reported to work on other Yotas. I will try the codes posted above and report back on whether they work or not.

One of our boys has a Samsung. All the rest of the clan are Apple fanbois. I may see if I can get him to put Torque on his phone and see if I can get it to work.

Re: OBD II Scanner - Transmission Fluid Temp

I use a cheap Bluetooth OBD II Dongle and the Torque Pro App on any of my android devices (I have a phone and a double DIN Atoto A6 Android headunit as a stereo) with the following custom PID to get both Pan and Converter Temp. Works great! Not sure why anyone would spend the dough on a scanguage when you can use this setup.

For sensor 1 (Pan Temp):

OBD2 Mode and PID:
21D9
Long Name:
Transmission Fluid Temperature 1
Short Name:
TFT 1
Minimum Value:
0.0
Maximum value:
220.0
Scale factor:
x1
Unit Type:
F (there is a degree symbol in Torque)
Equation:
((((E*256)+F) * (7/100) – 400)/10)
OBD Header to use:
left blank

------------------------------------------------------------------------------------------------------------

For sensor 2 (Converter outlet temp):

OBD2 Mode and PID:
21D9
Long Name:
Transmission Fluid Temperature 2
Short Name:
TFT 2
Minimum Value:
0.0
Maximum value:
220.0
Scale factor:
x1
Unit Type:
F (there is a degree symbol in Torque)
Equation:
((((G*256)+H) * (7/100) – 400)/10)
OBD Header to use:
left blank

This is exactly what I was looking for. Thank you!

I wish there was something that worked with Apple but I will happily buy a dedicated device to use with the Trucks if I can make this work.

What year is your truck? And do you know what Bluetooth dongle youre using?
