Comes with everything. So instead of 15 things on the wall, I have one box on the shelf. Best shifting 604's I've built. Period. The Sure Cure kits are consistent."

I do 8-10 units and use five or six Sure Cure kits a week and none of them have come back. Customers say their cars haven't shifted that well since they've owned it; they're very impressed."

I don't know how the hell I've built transmissions before. With the Sure Cure kits, you order one part number and you have all the parts you need."
