Transmission Fluid Temperature

Has anyone figured out if it's possible to get the Transmission Fluid Temperature through Xgauge on a scangauge II?

Re: Transmission Fluid Temperature

I got an email from Scan Gauge, asking me to test an X-Gauge code for 2005+ Mazdas (see below). It didn't work for me, but I'm not sure if that's because my car is the 1.6L engine.

Try this code out for Transmission Temperature. It will most likely only work if you have an automatic trans, but if you do have manual please give it a shot also.

Thanks for helping us out.


Feel free to try it, and be sure to post back here whether or nor you got it to work on your car.

Thank you! I tried it this morning, and it works. I've been working on-and-off on this for about a year (trying to get the trans temp on the SGII). I knew the car reported trans temp over OBDII because another member on here told me about it, and I confirmed it at a buddy's shop who has a $3,000 laptop-based scanner/code reader, which shows anything and everything that's reported over OBDII.

Some vehicles just flat-out don't report trans temp over OBD (like my F150, which I believe is an older version of PWM, while the Mazda, I believe, is CAN). Newer (2004+) F150s report trans temp over OBDII, but not my 1999. The Mazda does report trans temp over OBDII, just I could never figure out how to program the ScanGauge to retrieve and display the data.

Here's a photo I took this morning. In case you're wondering, AFE is Average Fuel Economy (for that current trip). It's shown under the TRIP menu on the home screen, but you can use the XGAUGE feature to show it on the GAUGE screen.



For reference, I was told that normal operating temperature for all ATXs is between 175F-195F. Since the OEM ATX cooler on North-America-spec ATXs is a tuna can cooled by engine coolant, the temperature shown above is reasonable to me, since that means that the coolest that the ATF can be is the coolant/water temperature, or 198F (at the time the photo was taken). And I just finished my commute, which includes climbing two mountain passes and one very long, uphill on ramp.

Great - glad to hear it worked for you!!! And you're right - the Mazda 3 is CANSF. I guess if it worked on your car, that means it should work for all MZ3s in the N/American market. I'll shoot an email off to Linear Logic to let them know that it worked on a 2008 Mazda 3 S.

I'm still trying to find a way to get it to work with my MZ3, but no luck yet

Probably has something to do with the fact that the transmission fluid cooler on the 1.6L models is air cooled, and not the tuna can.

edit: I'm beginning to wonder if Mazda would have removed the TFT sensor completely on the air-cooled 1.6L engine models. If so, this would make my trying with the TFT codes useless. Anyone know where the TFT sensor is on the MZ3 and if it can be seen from below the car?

I know the layout of the lines from the transmission is different between the 1.6L and the 2.0/2.3L models, but I'm not sure what the sensor looks like. See http://www.mazda3forums.com/index.ph...072#msg3982072 for pics of my transmission and the lines leading out of it.

Re: Transmission Fluid Temperature

I believe the trans temp sensor is on top of the filter/strainer in the pan. So you'd have to remove the pan and the filter to see if it's there.

But reading through some previous messages, I read that the vehicle will kick the transmission back into "drive" if it's in manual mode and the transmission overheats, which has it's upper threshold apparently set at 215F. If that's the case, then either that feature (moving from drive to manual mode) is false and the car actually doesn't do that, or the number being reported in my pic above is not scaled properly, because I drive with the car in manual mode almost all the time (out of the 41,000 miles on it now, probably 40,500 were in manual mode) and never once had it kick back into drive.

I think it would have to be the former though, because I've seen the water temperature climb up to 217F while stopped on city streets where the ambient air temperature was over 100F and the intake air temperature was around 120F. So at that point, there is no logical way (that I can think of) where the trans temp could have possibly been lower than 217F, yet the car was still in manual mode.

I've also been to a friend's house several times, and his house is on a large hill that has a one-lane road leading up to it, that crests over three smaller, yet still very steep, hills. On the way up, I usually go 15-20MPH (any faster and it starts getting sketchy) and on the uphills, the water temperature will exceed 220F for a few minutes at time (until the car crests a hill and starts going downhill) but the car will stay in manual mode.

I'll check the car's manual later today though, just to see if that feature is mentioned and/or exists or not.

Damn - well I'm not about to go drop the pan to find out Just also realized that my transmission is a 4 speed auto, vs. your 5 speed. Given that it's an entirely different transmission, that makes it even more of a possibility I may not have the TFT sensor.

You could also just go back by your buddy's shop and hook up his high end scanner and compare the TFT reading from that with the scan gauge.

the interceptor gauge picks it up throught the obd II as well, i usually run about 195 or so, 205 if it's pretty hot and i'm on the gas

Re: Transmission Fluid Temperature

I just tried it on my 2.0 Mazda 3i (4 speed ATX), it didn't work.

Re: Transmission Fluid Temperature

The tran temp on my scan tool, which has the Mazda software shows the trans temperature at ambient temperature at cold startup, NOT at 122 degrees. IF the TFT was 122 degrees, you would not be able to touch the wet part of the dipstick. Additionally, the torque converter lockup valve, the TCC valve will only activate if the TFT is above 122 degrees. If it is under that, which mine always has been at cold startup, the torque converter will not lock up under 45 mph.

The manual mode will shut off and the TCM will automatically switch the trans to automatic mode if the TFT reaches above 215 degrees.

Calvin,
I think the scan tool you are using is not calibrated properly. At startup, it should be the same temp as outside temperatures. Your tool calibration reads about 50 degrees hotter than it actually is.
