I just purchased a 2020 Honda Passport EX-L AWD with factory installed transmission cooler with the intent to purchase and pull a RV in the next year.

I've plugged in a scangauge2 and I have programmed in the X-gauge Transmission Fluid Temp and the Transmission Fluid Temp-Alternative.

I'm getting the numbers 300-400 just sitting in my car in front yard (as I was programming in the scangauge2 and NOT while towing). I'm assuming these numbers are in Fahrenheit and they seem to be elevated a bit because when I google transmission temp I'm finding 175 degrees is normal and 240 degrees is elevated.

So now, I'm second guessing my scan gauge is wrongly programmed? Its brand new < 100 miles on the odometer so i dont think its a bad transmission.

So can anyone tell me what numbers I should be seeing?

I'm guessing those are Celsius values

well, i finally figured it out. I checked my version of scangauge2 and it doesn't have Firmware version 4.5 (which can accurately check for transmission temps).

I've never heard of a ScanGuage, where do you plug it in on the other end?

You plug the scan gauge in your OBD port (which is on every vehicle). Basically if you have a warning on your dash such as "check engine light". Mechanics (or you) can plug into your OBD port in your vehicle to see the specific error code which is causing a fault. So, a "check engine light" may just be a minor fault (which can wait) versus panicking and immediately towing vehicle to dealership.

You can also use scangauge to monitor other information which is NOT included in your dash.

For my new Honda Passport I visually see in the dash a reading for temp, RPM, MPG, and fuel gauge.

Scangauge can monitor other information (if you are interested) such as: manifold pressure, boost, MPG, MPH, RP, throttle position sensor, water temp, average fuel economy, trip fuel cost, battery voltage, intake air temperature + many others

I plan to tow at some point in time in the future so I wanted to be able to monitor transmission temps.

Can you download updated firmware at no charge or??? Please let us know what the proper temps are once you get the new software version. I was planning on getting a ScanGauge also when I get my travel trailer.

Here is the ScanGauge readings on my 2019 AWD:

Picture taken under following conditions:
2006 ScanGaugeII running software version 4.53 (upgraded 2019)
Outside temperature ~ 71 degrees
Driving on freeway, about 68-72 mph
Vehicle has been running/driving about 40-minutes, 50/50 city/highway
Driver only, empty vehicle (no cargo, no trailer), 1/2 tank fuel

7277


Transmission in 9th gear, driving in "D" mode, engine coolant 186 degrees, and Transmission Temperature 138 degrees F

I have noted transmission temperature as high as 165 degrees, during a 3-hour highway trip earlier during 95-degree summer, with 3 passangers and perhaps 25-lbs of cargo in back (but NO trailer).

Hey PANDA curious what does the 8.5 MAP designate? Been thinking about one of these in the future... (the perfect "and what would you like for Christmas" from wife)! After seeing where you positioned the ScanGauge makes my choice pretty easy which one to go with.

I get about the same #'s as PANDA. No cooler. I'm on v4.50, and initially I couldn't get either ATF or TFT to work. Ran a data logger and SG engineer couldn't figure it out. So GER TXD starts with 1E and Jeep (with the same ZF) starts with 1E. So I modified ATF to start with 1E and that worked.
This is from start up after 3 hrs. in a hot garage.
7282


btw - PANDA's MAP = manifold absolute pressure - and why isn't it negative? (vacuum and not boost)

No, you would have to send it in to SG to get it updated. As I recall the support section had a procedure/form for that.

I had to send off my scangauge2 to get a firmware update. Just got it back today and I was able to plug it in. So now I can check my transmission temps.
