Android OBDII Scan App (Torque) and Trans Temp

Has anyone used one of these programs to track transmission temps? I tow often to the race track but don't have a true temp gauge for the trans. With my new android phone I've run across some bluetooth OBDII readers that transmit lots of info and see that the ScangaugeII can do trans temp. Would this also work for this android app? If so the $30 for the sensor and $3 for the app is a much better deal and I can transfer it between cars.

I beleive the 4L60E has a trans temp gauge factory yes...?

Any thoughts?

I've been using Torque (free version) with a bluetooth adapter on my Droid for several months now. If you get it to read a trans fluid temp you will be my hero!

I've searched for hours and messed with all the settings I could find to no avail.

There IS a temp sensor in the trans available to the PCM, but GM has done something funky to make it difficult to access by OBDII

OP, this might help you... CAN communicates differently than VPW (older OBDII, like the '07 and older I6 TBs use)...

http://forums.trailvoy.com/showthread.php?t=60583

FWIW, there's right now a $30 off coupon for Scangauge, which makes it right around $130, IIRC... Much the same as using your phone as a GPS, you're somewhat limited by actually talking on the phone, or the wife or kids using it to surf the net, or whatever...

My suggestion is just to get the Scangauge...

It must be accessibly as the scangauge w/ x gauge can see the temp via the OBDII port.

Have you tried these standard PID codes yet? I'm just ordered a bluetooth reader off ebay today so won't likely have it for a couple weeks to mess around with. If it doesn't work I'm only out $20 where my auction is at right now and I'll just use it for the gf's car and as a code reader.

http://en.wikipedia.org/wiki/OBD-II_PIDs#Standard_PIDs

I am using this on an 06 Rainier, I did a quick search but didn't find much related to iphone/android OBDII readers on here. I'm not familiar with the difference between CAN/VPW. This is more a tinkering thing anyways as I explore all the stuff I can do with android (had a treo 800 before), if it works great, if not I'll drop money for the Scangauge.

I've messed with the PIDs some and there was even some discussion on the Torque forum about it. Like you, this is mostly just a tinkering thing

Im sure there's a way to make it work, I just don't know how...

Yep, there has to be a way. I'll try to poke around the fullsize chevy forums...IIRC they use the 4l60e as well and there seem to be a few more forums towards those trucks.

Would someone at a dealership be able to access the PIDs needed?

I have been wondering how well these bluetooth ports work with Android. Some applications seem to be hit and miss. Please keep us updated on what you find out!

I'd say this one works exceptionally well. Found the adapter immediately and have never had a problem making/keeping a connection. The O2 sensor graphs update with enough resolution to actually make them useful--which is more than I can say for the $100 laptop software I have.

The default PID in Torque is 221940 under GM's extended PID group.

Or... Perhaps you could actually read the information in the thread I linked too in post #3? Read the whole thread... It's not long.

So is the TXD the same thing as the PID? Sorry this is new info for me...I just wasnt sure if the were the same. I did read through your info so don't take offense.
