    PML designed this pan for vehicles with 4L80E, 4L85E transmission and needing a space saving, high quality pan.


    • 1 1/2 quarts of extra capacity over the stock pan
    • Less than 1 inch larger than the stock pan
    • Drain hole and magnetic drain plug for easy fluid changes
    • Finned for cooling
    • Heavy duty sand cast aluminum construction
    • Machined flat gasket sealing surface
    • Can optionally be machined for a temperture sending unit
    • The distance from the flange surface to the inside bottom of the pan is approximately 2.75 inches. This is the same as the stock pan so the bottom of the pan supports the filter. Custom filter or supports not needed.

    Typical Applications:

    • Muscle cars such as Camaros, Chevelles
    • 1993 to 1996 Hummer H1 (see note)
    • Custom hot rods
    • Trucks with skid plates
    • Vans

    Always verify your transmission and clearance. Vehicle configurations vary.

    PML makes three pans for the 4L80E, 4L85E transmission.

    This pan is not designed to clear the frame cross member found on some 1997 and newer vehicles. See the PML pan for 4L80, 4L80E 1997 and newer.

    PML also makes a 4L80E, 4L85E deep pan.

    Note for Hummer H1: This pan can fit on 1993 to 1996 H1 Hummers, but the frame cross member is very close. Check your Hummer to verify the clearance.

    Jaguar XJS models with the 4L80 transmission have a stock pan specific to the Jaguar. PML does not make a replacement pan for the Jaguar XJS 4L80 stock pan.

    Image shows the rear and driver's side of the pan where the drain hole is located. All pans include a magnetic drain plug along with the mounting bolts.

    On the passenger's side, the pan has a location that can be machined for an aftermarket temperature sending unit.

    If you would like PML to drill and tap a boss, the machining charge is per hole. A plug for the hole is included.

    The standard size is 1/8 NPT. If another size is needed, please call or email.


    GM 4L80 filters  Click on image to view larger.

    There are two different filters for the 4L80. This PML pan has filter supports to hold the filter in place. A filter extension is not needed. The filter supports are not designed to contact the bumps on the bottom of the late model filter.

    The installer must verify fitment and installation. Be sure to check that the filter sits correctly.

    Cable Bracket on Stock Pan

    Some stock pans have a bracket for the shift cable assembly attached to the flange.

    Our customer Darrell provided these Guidelines for Modifying the Bracket to work with the PML pan.
