I want to publicly thank Charlie (evil8) for the work he did to my 4L60E. He worked his magic and built me a monster trans that should hold up to the abuse and hp I want it to. I told him I wanted a trans that I wouldn't have to worry about with higher power levels. I dropped it off to him, with a deposit, and a week later it came back to me brand new. This would have cost me over $4500 from RPM, he KILLED their price. I'll post up more in here once the car is up and driving.
Thanks again Charlie!
