Well i recently had my tranny fixed cuz i tore the shit out of the drum shaft cuz my line pressure was to high. But now its fixed it works fine. I would go with nelson tune and with the transgo reprogramming shift kit, and replace the regular clutches with the ZPak clutches and a more stronger sun shell. thats my guess cuz thats what i have and it work awesome. Because before i installed all of this i still had metal shavings in the tranny.
