I hate to do this, but in fair warning to another potentiel dissatisfied customer, I must.
I purchased a 700r4 level 3 from them rated at 600 hp/ 600 lbs with them fully aware of my power levels. I sent them links to my website, talked to them and was assured it would hold. I installed per the instructions, called in to confirm pressure readings, and drove it for exactly five days with ginger throttle to insure no leaks, overheating, or shift issues.
Then I flogged a 6500 rpm 2/3 shift on the way home and heard a horrific crunch. Long story short they found a loop hole in the warranty, and refused to honor it. I ran an external tranny cooler instead of going through the radiator. A local trans shop confirmed there was ample cooling, and the cause of failure was not heat related.
I now run a full manual th400 with a 3000 stall and have no fear of ripping 7000 rpm shifts with it.
Nuff said.

Find a quality 2004R builder for the GNs.....they have been putting modded rides with those HP numbers down the strips for a long time.
The torq numbers those turbo guys lay down are impressive.
Artie who formerly worked at Dynotech builds some really nice 2004R on some really fast GN's is currently building my 2004R. This guy really knows his stuff. Its hard to find a reputable trans builder. I have seen this guys work. He is a member on this forum as NJVetteGuy.
If you want the best of the best, (in my opinion) contact Bowler Transmissions and talk to Mark Bowler (the owner) about what he might recommend. He helped me with my 4l80e trans behind my twin turbo big block.
