    48RE valve body worn out? But cores are scarce and rebuilt valve bodies too expensive?
    This kit allows you to convert 46RE or 47RE valve body cores into a shift-kitted 48RE valve body.

    46RE/47RE Core Requirements:

    • Has boost tube
    • Has 4-land switch valve
    • Has 3/16″ check ball in lower casting

    Component Requirements:

    You must re-use the vehicle’s original 48RE rooster comb (not included) on the 46RE or 47RE converted valve body.
