I'm working on an undertray for my car and have come up with some cooling questions for anyone that knows about such things. Both my oil pan and transmission case are aluminum and extend down slightly into the airflow beneath the car. Could blocking with an undertray cause any overheating? 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.
