Trans temp

[xeqshnr]

Ok so I have a bluetooth ODB2 adapter on mybYukon and am using the Torque app on my Android phone. Works great, lots of cool things it can measure. My problem is theres a guage I can use to tell the transmission temp on it but apparently that info doesnt get transmitted from the transmission to the ECU. How can I make this work? is there a place to install a factory sensor on the tranny?? I dont really want to install a physical guage because I would only use it when towing and my phone would work fine. Actually better because it could data log the temp on trips.

must be something with your software hardware, combo. the pcm does register it. it is used by the pcm for operational use and it shows up for me using ScanXL on my laptop. but does not show up using a Scangauge 2 using the x-gage coding provided. contact the developer for a possible fix.

Good to know I dont have to add a sensor. Ill contact the Torque developers and see what happens. Thanks!

I think I found where I can make adjustments to how the software reads the sensor info. Do you happen to know the equation used to figure the temp??

was not much an equation as it was hex/decimal code that reads a specific stream of data variable so to speak. but hey knock yourself out and see what you can program. here is what the scangauge 2 unit can be altered with. just never got the tft to work thru it tho it shows up on the laptop scanner. still have yet to try the others too.

This is all new to me. Theres a place in the sensor managwment info that says equation. It does mention hex and another choice elswhere on the page. The equation box jus has several numbers but when you click on it it doesnt give you choices, just a.cursor to type in what you want. It also has two different methods for reading the temp.. Lots of variables here but ill.give it a shot. Thanks again

I know this is an old thread, but I'm curious if you ever got this to work. I just bought a Bluetooth OBD reader and will buy the app once delivered. Please advise what to do if you got it to work. Thanks

No progress as of yet. I havnt messed with it in awhile but I did send the developers a message. All they suggested was for me to download thier GM specific sensor software, which I already did. If I get it working I will post up how it all went down.

So any news??

You can add a gauge for less than $100. Why go through the hassle to try and make the torque app work?

I have scan gage 2 andbit is showing the trans temp

But keep in mind I found out that my 98 trans has been replaced by a 2001 model trans

My 95 shows trans temp with the right software too. It's gotta be something with that app for the phone.

tranny year is somewhat irrelevant as far as 1998 to 2001 units. it is the pcm that provides it to the scan gauge. the temp sensor has been there since it was a 4l60e or newer.

Then it should work right?

By the way I want to know what cause or why the transmission heat up? Some times when I am in traffic I noticed the trans heat up but when I am cruising on a high way it doesn't do that even though it did it yesterday

It cools like the coolant in the engine, no air flow over the cooler = higher temps. If your temps are climbing much more then 20 degrees then your fluid is probable past the point it can still protect and lube properly and needs to be changed at this point.

Tgank you I was thinking tge same I agree

If you are having problems with heat, get a bigger transmission cooler and maybe put a fan on it.

3500 series trucks sometimes had a bigger cooler and a fan.

True I searched locally for it as spare parts but I couldn't find it (they say it is too old!!) And I don't have the part number to search by the number maybe it was used for another model 2001 and up

I've been looking for something like that, do the coolers from the 3500 size and bigger just bolt up? Or is there a lot of cutting and modifying required to get them to fit? I've already for a 3 row radiator, the oil cooler, and tranny cooler in the front of mine. Not sure how the spacing and size would work with swapping out the stock tranny cooler for a bigger one. I'm having my tranny rebuilt here shortly and am trying to take every precaution to make sure it lasts (including having a reputable shop do the rebuild).

I assume that it should be a direct fit using the same fitting as tge small one

I really hope so
