Want leak-free performance? RTS leak-proof pump gaskets will stop problems. These precision-cut, slightly thicker gaskets deliver the proper fit and function to seal your C4 transmission front pump. Stop the leak with RTS leak-proof pump gaskets.

USA made interface gasket material is .8mm thick compared to the original .4mm gasket. Crucial areas of the gasket have been added to provide more sealing surface. We also recommend applying a slight smear of Loctite 518 flange sealant for a bullet proof seal.
