GM Trans Temp Gauge Install?

I'm interested in installing a temp gauge in our 6L90e transmission. Has anyone done this?
I'm struggling with where to place the sending unit. This trans doesn't appear to have a "test port" so, it looks like either I weld a bung on the pan or splice it in the return line.
Any thoughts or experience?

You should put the temp sender where the fluid gets the hottest. Depending on your driving situation and the age of your transmission, that could be in the torque converter or lockup clutch, in one of many planetary gear sets, one of the many clutch packs, in the pan, or at the inlet to the cooler. (there may be other locations too) Get the picture? If you are headed for transmission issues, the fluid temperature varies all over the place depending on what the transmission is doing and how much power you send through it. There is no average temperature everywhere at every time. The point is, . . . . . don't overload the transmission and chances are, you'll be fine.
