Tcm Location

Does anyone have a pix of the TCM while installed in the truck? I Have NO Idea where it is. I have a 08 sierra 5.3 . I am looking to send my ecm and tcm out to wheatly for a tune. Thanks for the help and sorry for the NOOB question.

dont have a pic..... but pop the hood and it will be right in front of you on the right. a big group of wires plugs into it. the one you see is the ECM and when you pull that one out you will then see the TCM behind it. the big one on the left is the ECM the smaller is the TCM
