    PML Design and Benefits

    PML designed an extra capacity, heavy duty pan for the GM 8L90 transmission. Our design includes these benefits:

    • Extra capacity
    • Finned
    • Drain hole and magnetic drain plug
    • Work with stock filter and gasket
    • Heavy duty sand cast aluminum construction

    Since there several different stock pans, PML designed a pan to replace all stock pans.
