The sensor is located on the Transmission Fluid Range Switch (valve body). And reports trans temp to the PCM regardless of whether you have a Temp Guage on your cluster or not.
Also, something to note, the thermistor faces downward and is directly exposed to the fluid in the pan.

Placing the sender in the pan, allows the temperature of the circulating fluid to be measured. Fluid come from the transmission cooler goes straight to the lubrication, and consequently cooling then goes right to the pan.
As for fitting it into the pan, i cant see how it would be easy with the stock pan as its thin. Now my TCI deep pan actually has a sender hole pre-tapped.

There are nearly two dozen fluid exhaust ports in the 4L60 trans, all of which dump the fluid right into the pan.
And each clutch pack itself has a corresponding apply piston. Just because i'm using those words doesnt mean that i'm refering to the engine exhaust or pistons.

i bought a remote fluid filter with auxillary port and put the sneding unit in there so it reads the exiting temperature of the fluid. hits 200 on hot days. once it hits lock up easily falls to 165. one reason the pressure port may read higher is because heat rises? hotter fluid on top of the cooler fluid.

ok..
I did a little research today, and hooked up my laptop to the PCM, and did some data logging..
I have my sending unit screwed into the port right above the shift linkage...
My temp guage showed to be at about 175* in stop-n-go traffic tonight on I-10..
looked over at Autotap, and the PCM showed it to be a few degrees off and a bit higher at 178*.
at no time during my drive this evening did the trans temp vary more than 3 degrees from the PCM..
Thats about as accurate a reading as your going to get..
