In Chrysler 62TE units, 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 shim will not distort. The rubber grommet provides positive sealing at the passage. Sonnax Low/Reverse piston retainer oil feed seal kit 92106-03K can be used to replace late-style gaskets with a large feed hole. For four-speed applications with early-style gaskets, use 92106-01K.
