Sonnax Sure Cure kit SC-6L80-6L90 for GM 6L80 and 6L90 units is a comprehensive reconditioning package featuring the best Sonnax products developed to help rebuilders restore and enhance transmission performance. Sure Cure components are the same Sonnax parts sold individually to resolve common valve body complaints as well as other transmission problems. The high-quality Sonnax parts in each Sure Cure kit repair worn areas and protect the transmission against future damage. Plus, each kit comes with an easy-to-read, step-by-step installation guide that covers the inspection and repair of the most critical areas of the valve body.
This kit and its instructions showcase the use of the newer pressure regulator valve 104520-16K. If you have an earlier kit 104520-07K that has the earlier pressure regulator valve, that requires pump drilling.
