Where to best locate trans temp sender?

I want to add a transmission oil temp sender/gauge on my 92 740
turbodiesel wagon since I am pulling a 1500 GVW trailer now with it.
I found that there is already a 10x11 trans. cooler mounted in front
of the AC condenser coil assy. So I could easy just stick a 1/8 npt
sender unit into that with some high-temp RTV. The other way would be
to get a brass tee, and tee the sender into either the supply or
return trans. oil line. My only concern about doing it the first way,
the easy way, is that maybe with the outside air impacting directly on
the trans oil cooler and sender, maybe it would read a lower
temperature than actual?

I believe the normal water temp for the engine is 192 deg. , should
the trans oil temp never go above 200 deg also?

A '92 Turbodiesel? Where did you get that?
