Use Mobil 1 or GM full synthetic trans fluid. The "only" difference in fluid, it seems, is that the fluid that does the best by not breaking down in heat is what works.

I am no expert, but I know my crap lives. We had a semi synthetic autozone mix in my 2004r before it sold. With 1 year of racing in the low 11's and then 2 years in the mid 11's, there was almost no clutch wear.
 
make sure.

you install a big! trans cooler,
I run std ATF, have no problems,
ask the trans guys, I'm sure opinions will vary.

DexIII and change it once a year
 
Big cooler and any dexIII. Change as needed. I change mine 2-3x/yr. Be sure to drop the pan every time you change to inspect and clean magnet off.
