It unsnaps from the shroud, IIRC their is a lever you pull on to unlock the harness from the TCM. I have removed and replaced mine several times to remove the upper shroud to bolt the TCM in place. IF you cannot figure out how to remove it without posting to a site should you even be under the hood...? Common sense dictates how easy it is....!! Second, spray some WD-40 or silicone spray to ease in removal and re-install, while you're their spray some of the same on the ECM connectors, almost broke the lever when I removed mine....:D

I would go out and take some pictures, but, I have since bolted the TCM onto the shroud and it no longer unsnaps from the shroud as I have read the clips have failed letting the TCM hang loose....
