I'd suggest contacting Dave at TEP. Be specific about the parts/way you plan to make the power (SC/Turbo/Nitrous etc) and he can guide/help you with the best way to get a trans to hold. I know that currently they are working on a few different things over there to improve even further on the already great transmission they put together. Some cool stuff that'll help us out in the weaker link areas on our transmissions.
