Scanguage II, Trans Temp, 2001

[EricUT]

Hi, I've read so much conflicting info on this, mostly in old posts, so hoping to get a recent and definitive answer. Will the Scanguage II provide (accurate) ATF temp readings in my 2001? I'm going to have to use this thing to tow a fairly light camper trailer for at least the time being and want to monitor the temps closely, would love to do it with an SG2 vs some ugly gauge pod if I can!

It should. There may be an "x code" to put in in order to display that reading. I believe the x-codes may be specific to either model year or at least transmission (4spd vs 5spd). Do a search for the transmission temp code and you should be able to find it. I think SG even has a finder tool on their website for this purpose.

It definitely will. I use one for towing a 4500 lb travel trailer. Here is the xgauge for TFT

This is the best news of the month, thank you

You got me wondering! What is "too hot" for trans fluid temp?

I'm no expert, but most of what I've come across follows this pretty closely

This is a good chart, thank you for sharing. It's also reassuring- while towing my ~3000ish lb camper, spinning 34" tires and even going uphill, my trans never saw more than 175* at the extreme peak. Generally it's happy to run around 160-165* while towing, and between 150-160 when not towing.

I have seen up to 215 degrees going over Monarch Pass and that had me sweating hard. Good to see that is not desirable, but not that bad. I just lock my transmission in certain gears when going over mountain passes now. This usually keeps the temps below ~180 or so. I have a 99 4 speed so that tends to be 2nd or 3rd gear.

The Scangauge II has been one of my favorite mods.

The mount is from @CruiserGarage.

For sure this works on the pre 03 transmissions ? I thought they had the same A343 as the 80 series and there was no option for trans temp on those.

Did yours show the ATF temp right away after setting it up? I bought the gauge and configured the xgauge easily enough, but not giving any readings for it.

LOL, this may have answered my question I posted at the same time.

Yep I tried every code I could find on my 97 and never got it to register. Should be the same transmission.

Great news, I found these slightly different codes in another very old thread, and now I'm working fine. There must be a difference over the years. Might be worth a shot if you've still got the SGII?

It's a beautiful thing! lol. I'll get this thing properly mounted when I get the overhead mount from BenCC

Does anyone know where the temperature sensor is for the trans temp? I just bought a scan Guage as well for the same purpose of monitoring trans temps, but curious as to whether I'm reading torque converter temp, or pan temp or what.

Ronny Dahl just came out with video on important gauges, and the scanguage is frequently mentioned.


Now I'm wondering if there is an x code for exhaust gas temp as well

Adding a data point that this set of codes worked for my 2000LC.

I have a 2002LC and have tried various codes on posted on mud and experienced high fluctuating atf temps. I was able to locate these codes on scangauge au website but the readings are in Celsius.
