Anybody convert 5th geb ZL from TR6060 to automatic ????

Looking to make the switch. Cant find much info on anyone who has converted from TR6060 6 speed to an auto. Preferably the 6L90 or a TH400. My car is heavily modified. It makes 904HP to the wheels on E85 and meth. Fully built internals. We race mostly 60 to 130 and I could shave some time with the auto. So, anybody done this before or can you steer me in the right direction? My builder is pushing me towards a TH400. I like the weaponx stage 3 6L90 but I'll be closer to 1000HP wheel very soon and I'm not sure if that unit can hold up....Looks like a few CTS V cars have made the switch but not many details on how they did it. I appreciate it!
