The oil temp would be somewhat moderated by the fact that the engine itself is cooled via the radiator. The transmission has an ATF "warmer" that has coolant hoses running to it, but I don't know if it also helps cool the transmission. The "warmer" has two warmer and two bypass hoses running to it, and I've no idea how it functions.
I may be able to tap into the ATF temp sensor with a multimeter, but this will only give me a voltage reading. I wont' have a good idea of how that reading correlates with temperature.
