06 GMC Yukon XL TCM Location?

Does anyone know where the TCM is located on a 2006 GMC yukon XL 4x4, 4l65E transmission?:runaround:

There is no seperate tcm, the pcm controls the trans and engine functions. Btw, welcome to AF.

This is great news, I have been looking all over for it. I heard different information regarding the location of the TCM, but could never get a clear cut answer. I think GM introduced the separate TCM in 07. But again thanks, I'll quit looking now.
