Just bought a Scan Gauge II w/ XGauge for a 1Gen Tundra V-8.

It's going to tow < 3500 lb from Texas to Idaho (climbing).

How do I monitor ATF temp w/ Scan Gauge?

So when did they add this feature? The other threads on this product say it is not available?

It is NOT available as of yet.

The Scangauge people told me a few weeks ago that they were " working on it "

I hope they make it work soon..............

TNX.

So much for the $170 just spent.

I guess the only thing useful left is MPG.

Before you buy, you might want to investigate first !

Not only you get the MPGs but also the codes you might have, and you can clear them.

You also get HP, and a myriad of additional info that comes handy if you ever need to diagnose problems

product worth what ya paid as it is :tu:

Also, from what I understand, as soon as the Trans temp feature is available, they can reflash our existing scangauges with the new version for a fee. Of course we will have to send it in to them to do that.

so are they going to install a sending unit and wire it because the temp sensor i do not think will give a reading till it reaches the idiot light temp which is too late or probably close to it. I would just spend the 100.00 bucks and do your own sending unit kit with all the parts included, just do not put it on the A pillar if ya have srs air bags!!

So why did you buy it?
Makes me think you don't research things before you buy them. :td: Not a good way to spend money. Hope you learn from this. Here's the manufacturer's webpage describing the product's features: ScanGaugeII - Scan Tool + Digital Gauges + Trip Computers (http://www.scangauge.com/features/)

In case you're wondering how I got that info, it was a Google Search Results 1 - 10 of about 417,000 for scangauge ii. (0.11 seconds)

Hey ***.Admin,
I was going to give you a hard time for giving this guy so much grief - - - until I saw his join date and # of post. Dude should have done a search, should know how by now.

Every so soften I get mad about the folks at Linear Logic stringing us along and failing to crack the ScanGauge codes for trans temp for our trucks. It motivates me to root around the web and see if I can find any potential clue. The fan base is surely large enough! Today I came across this set of XGauge codes.

So I just tried it on my 02 Tundra 4.7L and it looks promising. My truck set in the garage all day today. It was about 90F outside. The initial reading was 78. It didn't change so I held the brake, shifted into D and revved 2000 rpm (convert stall) maybe 15-20 seconds then the numbers started to climb. I shifted back into P and idled for another minute or so while the numbers inched up to 111 peak. After the better part of another minute the number started sinking back down. This looks promising indeed.

Was wondering if those codes will actually display Transmission temp.

Any luck anyone ??

I'll try the codes tomorrow...

That sounds very promising. I am going on a long trip with my TT this weekend. I'll pop those codes in my SGII and see if I notice the numbers rise as I go through some steep inclines. If the numbers go up as the load on the tranny does that might be what we have all been waiting for. Great job digging those codes up.

I agree, thanks for digging those up and posting them. I just inputted those numbers into my scangauge. WT is measuring 86 degrees and the tranny temp shows the same. I hope to test this out tomorrow. Since I have a fan hooked up to the tranny cooler I should be able to see a significant difference in temperatures when I turn the fan on.

More results to come...:pray:

Tried it on my truck and it truly works. Shows temp in F but would have preferred C readout instead. AT temp shows ambient temp if truck has been standing overnight. Stop-n-go driving brings the temp to 154F, S-N-G driving to freeway driving brings temp down to 120-130F. Truck is empty only driver. Truck has Royal Purple Max ATF full syn in the auto trans.

You should be able to change from F to C within the settings.

If this truly works, I may just have to buy a SG now! The main feature I wanted was Trans Temp.

I'm with you. This would put me over the top on this decision for sure. I've been waiting a few years for this.

Keep the tests coming, like does it work on an ' 06 4.7? Many thanks!

Any news?? How are things working out with the Tranny Temp codes? Choppin at the bit here... :-)

I tried the new codes on mine but it only shows the name I put in. Nothing else. I checked to make sure I did it right and things look good. Not sure, why though. At least it is working for some of you. I wonder if the newest version wont work with this code. What version are you guys running?

I'm using version 3.17.

So after doing some hwy (around 55mph) and city driving, I'm not sure if the codes are for the tranny or something else.

I had the numbers go up to around 156 and was at a stop light. I flipped the switch and the numbers didn't change. I did this multiple times at different temp ranges ( 140's, 160's) and everytime I flipped the switch to the fan, no significant change.

So either my fan is not doing anyting to cool the tranny down or maybe that code is for something else.

If it's the fan, maybe it's too close to the tranny cooler. I should try to move the fan away an inch or so and see if that provides any positive results.

If it's the code, could it possibly be the code for the oil temp?

More test as time permits....

Thanks guys! I wonder too if the codes posted are for the older models (pre vvti)? Or, maybe they just have not been released for these trucks yet and those codes are for other Toyotas vehicles.

Mines a pre vvti (2000 model). In anycase, I don't think it matters on the model. I think the codes are based on brand line(toyota vs GM vs Ford vs ...), gas vs diesel vs hybrid vs electric.

Well now I'm not sure why mine won't work. I have version 3.17 as well. Just checked the code again and everything looks good. Has anyone else with a 2005+ gotten it to work?

I guess it varies on the protocol it uses. I think toyotas made during or after the year 2004 uses the CAN protocol in the OBDII system. Older trucks uses the ISO protocol.

hmm... I just put them in and I'm getting the same results with the number increasing under a load... could it be! Does anybody have any numbers on how hot the tranny normally runs in drive and the various gears on a 2001?

I tried it the other day on my '05 and no luck. I was pumped for this! I double checked the codes and as said, all I get is the name I put in. Oh well.

I tell ya, no tranny temp, no clear corners (for DC), no supercharger. They really screwed us 05/06 guys. I love my truck though, what can I say.

Well I finally got around to plugging the codes above into my SGII today. I named the gauge ATF and started the truck but it did not read anything. I highly doubt that it is dependent on movement of the vehicle, but I'll find out when I drive around. Unfortunately I can't do that right now since I think i drained the battery after re-installing my UniChip (it just came back from the factory, see here (http://www.tundrasolutions.com/forums/1gen-tundra/170030-my-unichip-story/) if interested).

Just checking in. I see the codes didn't work for everyone. Sorry 'bout that. In my case, '02 Tundra 4.7L, I am sure the numbers are right. They go up and down exactly as I would expect.

Someone asked about what temp numbers are good or bad. Hopefully this helps.

I haven't tried them in mine... from what I have gathered they don't work in the later model Gen1s.

Glad it is working for you!

I just came upon this post. I bought the ScanGauge II during the group
buy here. I must've ignored the original post because the question about
how to check the ATF temperature had been beaten around so often.

I'm definitely interested in checking this out. I have the same year
as kamperbob so hopefully it works out. Thanks for the info.

John

Well I entered the codes provided by Kamperbob and was successful. By
successful I mean it's reading the temperature of something, which I'm
hoping is the ATF.

I drove my truck today for the first time since entering the codes last night.
It was in the mid 20's (F) today and I noticed the temperature eventually got
up to about 135 F in mainly stop and go traffic. While driving a couple of
miles on the highway it dropped quite a bit. Tomorrow I'll be driving quite a
bit more so hopefully I'll be able to get a better idea of what's going on
with it.

Thanks again Kamperbob from a fellow '02 owner and Central Masser!! You're
in luck too, you're one of the few people that I've been able to send points
to.

John

Another way to check operation of the trans temp reading is to note when the torque converter locks up. In OD it acts like a 5th gear at ~45 mph min. In D (OD off) it acts like 4th at ~40. When the TC locks, tranny temps plummet.

Cheers
KB

I checked it out today and it worked. When I hit 45 mph and the tourque converter
locked the temperature dropped from 145 F to about 111 F. Thanks again.

That's great! I hope us later model Gen1 folks get some codes so we can enjoy that as well.

Happy Holidays!

We're a little slow at the Base today so I snuck out to my truck and plugged in the ATF temperature numbers......on mine........I think it works! :D
It's in the low 40's here today.....really windy....the truck has been parked out there for several hours.....I had it running as I programmed the SG.....hit save after naming it "ATF" and the gage started at 80.......one quick drive around the parking lot and down the street made it climb to 100 or so....I'll know more after tonights and tomorrow mornings drives......but I think it works! :lol: cool!

I had some time so I decided to check it out. I tried every transmission fluid temp code I could find on the Scangauge Xgauge guide. None of them worked on my 06 DC. At least now I know and can stop wondering.

Congratulations to those who could get it to work on the earlier Gen1s. I guess it is like stated somewhere around here the newer ones are CAN. I did notice the code that works is the VWISO code, go figure. I suppose one could spend there time guessing and inputting codes... that could take a lifetime though.

Won't hold my breath on this one, but maybe the folks who produce the Scangauge will eventually get the code.

Was it 2005 when vehicle codes changed, perhaps due to power train changes?

I'm pretty sure mine is working.....This morning at startup Intake Air temp was 35, ATF temp was 33......the ATF quickly rose to 115-117 on the drive....so I think I'm measuring temp of something....I hope it's the trans fluid! :p

According to the attached list, Toyota Tundras didn't start using the CAN protocol until 2007.

And, if someone can make sense out of the information, here is some light reading: http://en.wikipedia.org/wiki/OBD-II_PIDs

Check out Kamperbob's post #35 in regards to the torque converter. That's what
convinced me that it was reading the ATF and not something else.

That leads to the question of why doesn't it seem to work in the 05 - 06 Gen1s. When I did input the codes I checked them a couple of times to make sure I was accurate. Of course I caught myself a couple of times with a number off... and then retried. Maybe it is the difference in transmissions... 00 - 04 had the same or very similar 4 speed, correct? A different OEM temp sensor system for those 5 speed transmissions.

I'd wager that's exactly it. However, I still think that the appropriate PID (Parameter ID) is available for the '05-'XX ECUs; it just hasn't been "found" yet.

I agree. With some dumb luck maybe one of the many folks who want it will stumble across the proper codes. We know there is a temp sensor and a tech with the proper scanner can hook up and read the temp... so it is definitely there.

Finding it would probably be like finding the link to make the keyless entry into an alarm on the DCs. The OEM key fob can unlock and lock the doors and it can set off an alarm with the panic button. Yet, when I asked the dealer how to upgrade that alarm they said that was not an option. :( Seems like the flick of a switch, a harness adjustment (jumper installed or removed), or some computer programming could have easily achieved the upgrade. Some one is missing something here and I don't believe it is me. :loco:

:focus:

Happy Holidays!

Just tried the codes on my '01. It seems to work! Thanks KB!

I'm glad this is helping 04 and earlier folks. For those with 05 and later hang tough. I agree the codes exist; they are just hidden.

Tried it on my truck and it truly works. Shows temp in F but would have preferred C readout instead.

I have a 2009 LandCruiser which doesn't seem to work with the codes. However, you are one of the lucky people where the code is known, and proven to work.

If you want deg Celsius instead of Fahrenheit, try this set of codes and let us know if it works for you. The only change is the MTH values.

Subscribing, anxiously looking for tranny temp for newer model year Toyotas!

I have a 2005 Sequoia, and have always wanted to measure ATF temps since I tow a trailer. I emailed them a few weeks ago and they said that "there's a good chance" it is now possible using a different XGauge with an 05 than the one mentioned in this thread. I had already started a different thread about it before seeing this one....here it is:

Away from the el computero

I just dropped the code into mine, I only took quick trip to home depot, but whatever it is measuring fluctuates between 100-165. I am going to pay attention to it on my work commutes, it seems to be trans temp.

Torque Pro Android app + Bluetooth OBDII adapter = the winner.

Thanks for that link. I checked it out and it seems the missing piece (at least for me) is my older firmware version. They claim the trans temp can be read if you have version 4.0 or later. I've got version 3.17. The tough pill to swallow is that they want $25.00 to upgrade the firmware. I already paid a premium for the gauge and I can't even tell you how p'd I be if it didn't work.

I might gamble though... :D

No not really. Besides I've had my SG for a couple of years now... so I wouldn't feel right even trying to return it. Seems to be with what they charge for them that they should give you one or two upgrades. Oh well, I"m probably going to risk it and send mine in.

I would like to get a temperature gun to check my trans pan temp and compare it to the reading on the gauge. I think it's reading right but I'm always curious. Besides, I need a temp gun for barbequing. :D

#59 thanks for following up, tundrunk. IR guns also rock for dutch oven cooking! Not to mention tire temps. Sorting out the bar babes? Hmmm...

#58 you missed my hint, Dinosaur. Here's what my friend in CO did today. Walked into AutoZone and confirmed return policy. He even got the guy to install it for him! Minutes later he's rocking on with tranny temp in his 09 Tacoma. Not Tundra but a good data point me thinks. Maybe your AZ dude won't install for you but you know it's wicked trivial. If it works, confirm the version. Sound like a plan? :)

The nearest AZ is in the "city" 1 1/2 hours away... however, I just happen to be heading that way tomorrow. :D

Also, I'm not sure how much it would mess up the ECU's calculation fer using that sensor. :(

Has anyone confirmed those 05/06 codes listed above work?

Thanks.
