I would think you are correct by putting it in the line going to the radiator.. there or on the side of the transmission pan if there is a good place for it.
seems like in the pan would be like getting the temp in the output side of the rad, its already been cooled so the temp is not accurate, at least how i see it.
what about any ports on the trans? any of those all time flow and :at the end of the line" before leave the trans?
