I am currently designing an undertray for my Mazda Miata. The tray will be used in conjunction with a new front end and rear diffuser in an effort to generate downforce or, at the very least, look pretty when the car is upside down. 
This is more of a pet project than anything. I'm not expecting great results, but I don't want to create any problems, either. My primary concern is transmission cooling. A sealed flat bottom will inevitably result in a cooked gearbox. Seeing as I've already eaten four due to sheer HP, I'm not fond of this idea.
Getting to the point, what sort of ducting should I incorporate to create airflow over the transmission? A NACA duct probably wouldn't provide enough flow to be effective, and all of my other ideas would create too much flow disturbance to make the undertray worthwhile. I would prefer not to install a transmission cooler, but I won't rule it out.
Thanks in advance.
