Vehicles with a 4T60 or 4T60-E transmission often have oil leakage at the side cover to channel plate inner gasket. The time-consuming and difficult task of replacing the inner side cover gasket often does not eliminate the leakage. The failure of this gasket can be caused by 4th clutch heat, side cover corrosion, and/or potential crushing or splitting of the gasket when the side cover pan nuts are torqued. Sonnax offers a leak repair plate, 84995-01, designed to fix the leak without removing the side cover or replacing the failed gasket.
For use with stamped steel side cover.
