    Product Description

    Part number: 279701
    Fits: TH400 / 4L80E

    Why the OEM shaft fails

    The OEM shaft has undercuts behind the ring gear and clutch hub splines. Their sharp edges and reduced shaft diameter make it prone to stress fractures. TCS eliminates those undercuts, relocates the oil holes to the bushing surfaces, and adds one oil hole for the planet assembly.
