The transmission param of diffuse shader is "hidden" by default (hollow circle). You can only access it in the graph editor, by manually connecting the texture node to it.

Thanks! I think I'm slowly getting it.... I did find the transmission node on the diffuse material and here is what I did. I created a float texture (using a spec map) connected to the transmission node on the diffuse material. Just for laughs I also connected a scattering medium to the medium node on the diffuse material. These all got connected to a mix material and the other side of the mix is my glossy material with diffuse map, spec, and bump maps. The mix setting of 0 is all white, and as you up the setting it gets more like skin. I still can't figure out how to get the transmission param in the graph editor via the diffuse material.....it never shows up in node inspector...

Something is happening..... here is a quick render
