I haven't tried with a '15, but these are the settings I used on my '12. How are you looking to get this data? Scangauge? Torque app?

I haven't tried with a '15 but I monitor the trans temps in my '14 using the android Torque app straight 'out of the box' with no customization.

 

Do you remember the specific name of the Sensor you used for Transmission Temp (there are several different "extra PIDs" which include different Trans Temp PIDs)? My friend has access to Torque, but we couldn't find a Trans Temp that seemed to work.

 

I'm using UltraGauge. I tried on a friends 2008 Civic, with the above codes (modified for UltraGauge), and it did work on that vehicle. Just doesn't seem to like my 2015. Thanx for the info!

 

I've never messed with the pids on torque. Trans temp has just always been an available option.

Cool, I'll give it a shot! What kind of readings are you seeing on Trans Temp and Engine Coolant temp on your 2014 (when not under a heavy load. Would like something to compare against.

 

Ideal transmission fluid temperature is 180F. Temperature under normal driving conditions should not exceed 220F.

Of course, it may exceed 220F under heavy load for short periods of time. This is not good for the transmission, but it is unavoidable. Cooling the fluid sufficiently in heavy load conditions would mean overcooling it in normal driving conditions. Overcooling the fluid is also bad for the transmission.

It's a shame Honda hasn't gone to thermostat controlled cooling circuits like lots of other manufacturers have. Ford has done that for the past decade in most of their transmissions, that way you can have the best of both worlds. Maximum cooling for when needed, and the ability to get up to temperature in cold weather.

We have an external cooler on ours because we tow with it, and it struggles to get over 120 in the mild winter temps we've seen so far. Not good for moisture accumulation, but my F150 hits 190 even in single-digit temperatures.

 

Was able to get Trans Temp readings on the 2015 Odyssey over the weekend using Torque's built-in PID and it did seem to mirror the Engine Coolant Temp. Back to the drawing board. I haven't seen any other info on PID options for Trans Temp for the 2014/15 Odyssey, but, will keep looking...

 

I wanted to bump this to see if anyone had further luck with the 2014/2015 models.

 

I thought I would also confirm that out of the box Torque mislabels the transmission fluid with a coolant sensor on 2014/2015's. Its identical to the coolant sensor so we know its incorrect.

 

Can anyone speak to if this is still the case or not? Is Torque Pro correct in trans temp readings for a 2014?
