    PML designed this transmission pan for 1981 to early 1990s Ford trucks and SUVs with the AOD automatic overdrive 4 speed transmissions.


    • Extra capacity
    • Fins for heat dissipation
    • Heavy duty sand cast aluminum construction
    • Thick gasket flange machined flat for a secure seal
    • Drain hole and magnetic drain plug included

    The AOD transmission needs a different pan than the AODE, 4R70, 4R75. The bolt hole pattern is slightly different. For AODE, 4R70, 4R70W, 4R70E, 4R75E, 4R75W transmissions, see PML part number 9685-2.

    For more information on differences between these 4 speed Ford transmissions, click here.

    Trucks and SUVs, such as F150, Expedition, and Mountaineer, and some cars have clearance and can benefit from the extra fluid of a deep pan. Examples of vehicles that may be able to use this pan:

    • 1980 to 1993 Ford trucks
    • 1982 to 1993 Ford Bronco
    • 1981 to 1992 Lincoln Town Cars and limos based on it

    There are many configurations so please check your vehicle to verify transmission and clearance.

    Cars, such as Mustang and Thunderbird and Lincoln Mark VII, may need the PML stock capacity pan, part number 9324-1 because many cars do enough ground clearance for a deep pan.

    Lincoln Town Cars and limos based on the Town Car have installed this pan. Work vehicles like limousines appreciate the easier maintenance and extra capacity for cooling to extend the transmission life.

    Installation Note: On some vehicles, the transmission cross member and mount must be temporarily removed so that you can drop the stock pan and install the PML pan. After installing the PML pan, be sure to reassemble. Thanks to Rick who provided this tip after installing this pan on his 2002 F–150 with the 4R70W transmission.

    Shift Lever Note: A customer with a 1967 Ford F-250 TCI AODE transmission noticed that thickness of the PML pan did not allow the shift lever full range of motion. He took the lip back about a 1/4 inch across a 1.5 inch line to get full range of the shift lever.

    Filter and Gasket

    PML recommends a cork or cork composite gasket.

    Filter requirements: For this PML pan, use the AOD 4WD (Deep) filter. Deep filters have metal pick-up tube.

    Information for reference only. Installer should verify appropriate transmission and filter and fitment based on the individual vehicle.

    The three round posts in the bottom of the pan are supports for the filter. These are cast into the pan. PML designed this pan with the filter supports to hold the the 4WD filter in place.

    Optional Temperature Sending Unit Machining

    Optionally, this pan can be machined for a temperature sending unit. There is a boss on the passenger/right side of the pan for this.

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

    The standard size is 1/8 NPT. Call or email if you need a different size.
