The guys in the GS forum have discussed this to some length. What I recollect is that for normal conditions, the factory set-up is more than adequate to handle the tranny heat. If you install a TC, tow or drive the car hard in a hot climate then you may see some benefits with a cooler.

Many cars are tested in Dealth Valley during development so for the most part, it is fine. If you are having tranny fluid issues or related heat problems, there is likely something wrong in the system that needs attention.
