Install this new design steel shim and rubber grommet in place of the original gasket of either design. Do not replace a new-style OE gasket with an old style shim.
The root cause of low/reverse oil feed leakage is piston retainer distortion and gasket material relaxing around the clutch feed hole. This prevents a positive seal around the oil feed hole on the piston retainer. The Sonnax steel gasket will not distort. The rubber grommet provides positive sealing at the passage. A Chrysler production parts change included a redesigned piston retainer and gasket. The Sonnax new design steel shim can be used to replace early- or late-style gaskets.
