Hey just wanted to let everyone know that the torque app finally displays the tranny temp and more!! Unfortunately it does not work with the cheap ebay clones (well mine at least). I emailed Ian about this issue and apparently my adapter kept throwing error and would freeze after 5 seconds, so hopefully all of yours will actually work. Neither of the auto PID's(method 1 and 2) work for the tranny temp you need to go to your setting and manage custom PID's. Once you are there choose "Add predefined set" for GM. Once it adds a bunch of PID's you can go to add a gauge and choose tranny.fld.temp. (I think that's what its called).
I also noticed that the fuel gauge never worked so I did some research on GM PID's and came across one that I used and it worked to make a Oil Life, Fuel Level, and also Engine Oil Temp gauge. This is the website I used

Since my ebay clone didn't work with the tranny I ended up buying this.

Oh and there is also a Trailblazer theme that looks much like our gauges which is cool, I was using that but for some reason it decided to make my gauges blue and yellow in the pictures.
Here are some of the gauges that I was messing with.
