Oversize Clutch Boost Valves require Tooling & a Fixture to install. I wouldn't be surprised if you found some distressed frictions & wouldn't be a bad idea to refresh the unit.
Thanks for the input. Not sure I want to spend the extra money on the fixture for the valve. Kind of wanted to avoid changing all the clutches as they seem to be more spendy for this trans as apposed to others. I know what the smart thing to do is though. Not sure about the Sonnax "zip kit" if it is something I should install.
