preferred protocol ISO 15765(29/500), may need to write in the initialization string: ATSP7
you need to create an external PID:
OBD2 Mode and PID:
222201
Long name:
Trans Temp
Short name:
Trans Temp
min:
-40
max:200
scale:
x1
Unit type:
F
Equation:
A-40
OBD Header:
18DA1DF1

Unit type and Equation necessary be refined

Okay, finally got a chance to give it a shot. 215 is really high, the coolant temp was 100° F and the van was only run long enough to pull into the garage. I’d guess this is more than twice as high as it should be.

I’m hex and PID stupid, can you give me some kind of tutorial? Tried it out, the 215 remains static as the car runs and moves.

See on the link, where I showed how you can pick the equation
open notepad, not to disrupt the formatting of text

Okay, here it is after sitting all night before starting up. Engine coolant temp is 60°.

After a short drive to bring things up to temp. Was about a 15-minute drive at low speeds. Coolant temp was 175°.

Change your equation and give it a look
for the variables you think might work.

Posting pictures using dropbox… this
thread describes how within its posts.

Looked like you tried posting pics
in the posts above… just sharing
what Ive found in the past.

My other concern which that thread
demonstrates… is Torque has a problem
with parsing a certain multiframe protocol
which might be the same as yours?

The raw hex data will be correct but the
Torque equation parser was not assigning
variables correctly and the equation did not
work.

I hope this is not the case for you.

(Sorry but my phone is not letting me
view your links).

Edit:

Does “U” match your ECT or EOT?
It acts like a temperature reading too.
Thanks for adding the screenshots.

@Tom

You may already know this, but a small tid-bit that has helped me in an endeavor similar to yours… the Microsoft Windows CALCULATOR has a pretty darn good PROGRAMMER “View” that makes converting (back and forth) between HEX / DEC / BINARY quick and easy. I ignored it for a long time because the default “View” is such a dumb / simple looking STANDARD calculator. But the other views are full featured, and it’s easy to cut and paste between it and your imported spreadsheets.

Hope this helps.

Wanted to say THANKS for all the help guys! Plugged it in and did some testing, it behaved exactly like I would expect from all the other vehicles I’ve monitored transmission temps. Here’s my final product, I’m fairly confident we got it right:

Mode and PID: 222201
Name: Transmission Temp
Minimum: -40
Maximum: 300
Scale factor: x1
Unit type: F
Equation: AA*(9/5)-40
OBD Header: 18DA1DF1

I’m glad I could help you out

I’m trying to get this to work on a 2011 Odyssey (EX-L) without any luck. Engine RPM and Coolant temps seems to work, but when I put this PID in it looks like I get -1 back since the formula result returns -41.8. Anyone have any thoughts on what could be causing this?

Thanks for the quick reply! Unfortunately that didn’t seem to work either. Any other thoughts? When I test the PID I do see data coming across but the result is still -41.8. I would think a 2012 would be the same as a 2011 unless the above is for a 6 speed and my 5 speed on the EX-L is different?
