I order to help the transmission get a little better cooling and a little better air flow to hit the bottom of the transmission pan, but at the cost of increasing drag slightly and possibly reducing downforce slightly, I decided to fashion a little scoop to add to the rear diffuser (rear panel that covers the transmission, diff, etc).
The next option was to add a proper HKS cooler, but that is a big step. My objective and exceptions were minimal for the amount of work put into this - Lower the transmission temperature by a few degree F during normal driving and allow for quicker cool down during track time.
