Transmission temperature

[SoNic67]

I am using an ELM327 from eBay (actually I have two of them and two of my friends have each one too). I had an original PLX Kiwi bluetooth for $100 but it was doing the same so I sold it for $50 - my loss.
Software is Torque on my Android device.
Settings are set in US units (degree F for temp).
And yes, I don't know why the transmission temperature rises so slow. Probably because there is no thermostat to regulate the flow trough cooler?

I would take it for a drive and get it up to operating temperature, then park the car, leave it idling, go out and try grabbing the aux cooler pipe (metal pipe, not rubber) and feel how hot it is.

Haha, I have one of those too, but I got rid of my android phone so I don't have torque anymore. Maybe I'll get a nexus 7 or something and use torque. I use dashcommand on my ipad now and it works great, but has almost every PID except for trans temp. Torque may be reporting an incorrect temp. What is the PID labeled as?

I did just get a 2011 copy of ALLDATA for windows for everything repair and maintenance and diagnosis ever... thanks cake boss.

Torque doesn't show PID's. You can load the extra set of PID's (Ford, GM, Toyota) at vehicle setup. Then you can just select "Transmission Temperature" on Fords (Sable, Explorer). GM vehicles have to use alternate methods (don't have sensors).
Maybe here you can find more PID's? Looks like is 1674?
I thought that maybe is not right, but when it was warmer outside, idling in stop and go traffic, I saw transmission temperatures in 190F range.

[Breeves002]

Hmm, well maybe it is. Only one real way to tell, but that isn't easy for trans. Did you see if the TC was actually locking though?

[SoNic67]

It is locking, I am not sure what's the cut-off temperature for lock-up.

[Breeves002]

I'll look around for a chart on it in my alldata... 1996 sable ax4n tc lockup chart. See if I can find anything like it haha. May say what the ambient/iat/ect/trans temp have to be at for tc lockup. All computerized crazy stuff haha.

[Breeves002]

Only thing I could find on the trans temp sensor. I'm sure it's a complicated computer calculation that was programmed in the PCM/trans computer.

[SoNic67]

It doesn't even say anything about TC...

[Breeves002]

I know, I know, but it lets you know what that temp sensor is used for besides TC! Haha, I'll keep looking if I get the chance. I have my factory 2000 sable manual, maybe something in there, but no search feature... I'll look through diagrams because I'm interested as well.

Unfortunately I doubt it is a chart because there are probably several factors that go into the decision for lockup the PCM/trans comp makes. If I could just find something about TC lockup vs. trans temp that would help.
