    • Prototype installations completed and PML is updating the pan design. Pictures in the INSTALLATIONS section. Our thanks to those who volunteered to help with the development of this new PML Mercedes 722.9 NAG2 7G-Tronic 7 speed transmission pans.

      PML includes new mounting hardware, magnetic drain plug and a custom PML gasket included with each pan.

      Please scroll down to sign up for our mailing list and for more information and pictures.

    Volume: 2.5 quarts over stock, approximately, the amount over stock varies since there are at least two different stock pans and level check tubes

    Dimensions: Click here for dimensions. , PML pan is about 2 inches deeper than stock pan

    Number of Bolts: 6

    Design Changes Based On Prototype Installations (June 2024)

    Our thanks to our prototype installers. Based on their feedback we are updating the design and making more pans. The updated design will have:

    • Better access for fill/level check
    • More clearance at front for frame on Sprinters
    • Area for attaching cables on sides of pan

    Benefits

    PML 722.9 pan has:

    • Fins and extra capacity to keep fluid cooler
    • Drain and magnetic drain plug for easy servicing
    • Heavy duty, quality sand cast aluminum contruction for strength and a leak-free seal
    • Boss for optional temperature sending unit
    • Does not use formed gasket or retaining clips, custom cork gasket and new mounting bolts provided with pan
    • Flat gasket sealing surface, thick flange, and custom PML gasket to eliminate warping and tweaking

    Because of the flat gasket sealing surface, a PML custom cork composite gasket is provided with each pan. The PML pan will not work with the OEM gasket and the OEM pan will not work with a PML gasket. Additional PML 722.9/NAG2 gaskets are available.

    The 722.9 NAG2 transmission is found in many Mercedes-Benz cars and vans and in 2012 and newer Sprinter vans. Configurations vary and other transmissions are possible. Verify transmission and space available for a larger pan before ordering.

    2021 Sprinter

    Mike installed a prototype of PML's 722.9 transmission pan on his View with a 2021 Sprinter 3500 Diesel 2WD chassis. Because of the tight space on the Sprinter, he needed to raise the transmission and move the exhaust to get the PML pan on. The front frame cross memeber is welded to the frame and could not be moved. He also removed the some material from the fins at the front of the pan. Once the pan was on, the transmission and exhaust were put back into place.

    Mike compared the level check tube distance above the flange and did not use the PML level check tube since his pan had a level check at the same height as the flange.

    Gasket

    PML makes a custom cork composite gasket for this transmission pan. One gasket is included with each pan. Additional gaskets are available: PML NAG2/722.9 Gasket

    PML NAG2/722.9 pans are not compatible with the OEM gasket. OEM pans are not compatible with PML gaskets.

    PML designed the transmission pan with a thick and machined flat surface to maximized the sealing area. The PML pan will not tweak or deform. The thick flange and bolts maintain even pressure on the housing for a secure seal. Retaining clips used with the OEM pan can cause deforming and tweaking of the OEM pan leading to fluid leaks.

    Included with PML Transmission Pan

    Included with PML 722.9 transmission pan  Click on image to view larger.

    PML includes a custom gasket, brass fitting to raise the fluid level check above the flange, magnetic drain plug with copper sealing washer, new mounting bolts and washer and a button screw for attaching a bracket (if needed).

    The PML pan does not use a retaining clip system to hold the gasket and pan on to the transmission housing. The retaining clip system can be difficult to use and people have reported that it warped the OEM pan, causing leaks. Using bolts on the thick flange on the PML pan improves sealing, minimizing leaks.

    Fluid Level Check

    The top of the level check on the PML pan should be the same as the top of the level check on the OEM pan. There are two OEM pans we know of. One has the level check at the same level as the flange and the other has a level check above the flange.

    The PML pan includes a brass fitting so that the fluid level check can match the pan with the level check above the flange. The brass fitting is only used when the OEM pan has the level check above the flange. If the OEM pan has a level check at the same height as the flange, no fitting is needed.

    Filter

    The PML 722.9 NAG2 transmission pan works with the OEM filter, including the new Smart Filter. The PML pan has supports cast into the bottom to hold the filter in place.

    PML designed the pan so that the fluid dynamics of the transmission are not change. The fluid pickup and checking the fluid level are the same with the PML pan as with the OEM pan.

    Drain, Fill/Level Check, Optional Temperature Sending Unit Locations

    The drain and fill/level check are on the driver/left side of the transmission pan. On the passenger/right side of the pan, there is a threaded hole on a little tab for attaching a metal shield found on many vehicles.

    This PML transmission pan has two possible locations for an aftermarket temperature sending unit. One is on the passenger side and one is on the driver side. These bosses are unmachined. Optionally, PML can drill and tap one of the bosses. There is a custom machining charge for this service. The default size is 1/8 NPT. Verify the thread specification of your temperature sending unit and contact us if a different size is needed. Select this option when ordering. This would be for an aftermarket temperature gage.

    Shield

    Many 722.9 NAG2 transmissions have a small shield attached to the right front corner. In this picture, the shield is circled in red.

    The PML pan works with this shield. The shield attaches to the PML pan at the tab on the front passenger/right side corner of the PML pan. This tab has a threaded hole and a screw is included for attaching the shield to the PML pan.

    Transmission and OEM and PML Transmission Pans

    The 722.9 transmission pan and gasket attached to the transmission with a retaining clip and bolt. The retaining clip system can warp the pan and lead to leaks. The PML pan has a flat flange mating surface and cork gasket and bolts on without the clips.
