In front of the battery you'll see the pcm. Further down on the side of the frame rail you'll see the tcm. Should have a blue plug on it.

I have a 2008 G6 GXP and it is throwing a 700 code for TCM and 716 for speed sensor. I just need to know where the TCM is located? Do I have to drop tranny to get to it? The PCM is in front of the battery on this model so I'm not sure if TCM is below the PCM or in the tranny?
