Although this pan is stock capacity, the thick walls and fins make it taller.
Number of Bolts: 6
Benefits:
PML designed this 722.6/NAG1 transmission pan for:
- Cooling — fins and aluminum construction
- Clearance — only 5/8 inch deeper than stock pan
- Drain plug — on the side for safety
- Secure seal — machined flat flange, no more retaining clips and formed gasket
- Strength — high quality, thick walls
The Chrysler/Mercedes NAG1, 722.6 family of transmission includes W5A580, WA580, W5A380, and W5J400.
Read about PML NAG1, 722.6 Transmission Pan Design (a new window or tab will open with a PDF file).
This PML transmission pan fits the 722.6/NAG1 (W5A580, WA580, W5A380, W5J400) transmission.
PML designed this 722.6/NAG1 pan for vehicles that do not have space for an extra capacity pan and still want the cooling benefits of finned sand cast aluminum construction and a drain.
Typical vehicles that can use this pan are:
- Jeep Wrangler 2012 to 2018 (maybe 2019)
- Mercedes Sedans
- Cars, trucks and SUVs that want a finned, heavy duty NAG1/722.6 transmission pan and have little clearance
Always check your vehicle before ordering to verify set up and clearance.
Check that the drain hole near the driver side front corner willl work on your vehicle. On most vehicles, the drain hole is located so that the pan can drain completely and fluid will not drain on to the frame or exhaust. Call to ask about custom machining if you need the drain hole relocated.
PML makes three pans for the NAG1/722.6 transmission. Need help figuring out which pan you need?
Check out this video or see Guidelines, below.
General Guidelines:
To determine which PML NAG1, 722.6 pan will work best, check how much space is available for a larger transmission pan. Look at the space from the stock transmission pan to:
- Frame
- Exhaust
- Ground (the transmission pan should not be lower than the frame)
- Drive Shaft
- Skid or sound dampening plates
- Other vehicle parts
Little or no space, like Jeep Wrangler and some cars:
NAG1, 722.6 Stock Capacity Transmission Pan (this pan)
Some space, like Grand Cherokee, some cars (Magnum, Charger), some Sprinter:
NAG1, 722.6 2 Quarts Over Transmission Pan
Lots of ground clearance, like Sprinter:
NAG1, 722.6 2.5 Quarts Over Transmission Pan
These are GENERAL guidelines. PML cannot tell which pan will work since vehicle configurations vary.
- 2014 Wrangler W5A580
- 2012 Wrangler JKU
- 2010 Charger 5.7 Hemi
- 2010 Mercedes C200 W204
- 2002 Mercedes S430
2014 Jeep Wrangler
Saul installed this PML transmission pan on his 2014 Wrangler JK 4 door, Unlimited, with the W5A580 transmission. He loosened and dropped the exhaust to drop the stock pan. Saul received an early version of this pan without the tab for the heat shield so he bent the shield a little to connect to the bolt.

2012 Jeep Wrangler
Scott installed this pan on his 2012 Jeep Wrangler Unlimited JKU (4 door). The frame cross member and exhaust routing made the PML stock capacity pan the best fit. These images show the stock pan and the PML pan installed. The middle picture shows where the exhaust comes apart and can be dropped so that the stock pan can be removed and the new PML pan installed.
Scott also documented his installation in this PDF file: 11132_installing_pml_nag1.pdf.

2010 Dodge Charger 5.7 Hemi
Chris installed this PML pan on his 2010 Charger with a 5.7 Hemi engine. His stock pan was rusted and the retaining clips distorted the stock pan. The PML pan won't rust and attaches with bolts, not clips. These images show:
- Stock pan, rusted and distorted from retaining clips
- Checking PML bolts on transmission to make sure they are the correct length. The gap between the bottom of the bolt head and the transmission is the width of the flange on the PML pan.
- Brake cleaner used to make sure surfaces and drain plug were clean of any bits.
- Stock filter from factory. Tab inserts into slot in valve body. Some aftermarket filters have a cheap latch, which do not work as well. If the tab does not insert correctly into the transmission, the pan will be difficult to bolt on. Stop pushing and check the filter.
- A floor jack is needed to re-install the cross-member.
- PML pan installed, looking good.

2002 Mercedes S430
James installed this PML pan on his 2002 Mercedes S430. He reported that the installation was "straight forward". A bracket at the front of the stock pan sits below the lip of the pan and swivels out of the way to drop the stock pan.

Gasket
Click on image to view larger.
PML makes a custom cork composite gasket for PML NAG1/722.6 transmission pans. PML NAG1/722.6 pans are not compatible with the stock gaskets. The PML gasket is not compatible with the stock pan. RTV may be able to be used in place of the gasket but the pan is designed to work with the gasket.
One PML gasket is included with each transmission pan. Additional gaskets are available. You can add a second gasket to your order in the shopping cart. If you need additional gaskets after ordering the pan, see PML NAG1 Gasket.
In this video, learn how this PML pan seals to the transmission housing:

Filter for PML 722.6/NAG1 Transmission Pan
Click on an image to view larger in a separate window. From left to right: inside of PML pan, stock filter
PML design this pan to work with the stock filter. The Mercedes part number on the filter PML used during design and development is 140 277 00 95. No tube or filter extension are needed.
Dipstick and Transmission Fluid Level
The fluid level should be at the same level in the stock pan and a PML pan. On many vehicles, the dipstick uses the bottom of the pan as a stop. The bottom of the PML pan is at the same location as the bottom of the stock pan.
Many vehicles with these transmissions do not have a dipstick and the correct fluid level is based on temperature. The cap for the transmission fluid fill and level check can say "See Dealer". The installer of a replacement pan needs to have the correct tools to replace the transmission fluid according to the factory instructions.
Shield on Passenger's Front Corner
Some vehicles have a shield that attaches to the retaining clip at the front, passenger side corner of the stock pan.
Pans available since March 2016 have a tab for the shield to bolt on to. For pans before March 2016, an installer would bend the shield to bolt onto the PML pan.

Drain Hole
PML places the drain hole on the driver's side, near the front of the vehicle (as shown in picture).
A magnetic drain plug is included with the pan and all the mounting bolts. The side location is safer than the bottom since there is less chance for damage than on the bottom. There is still easy access for maintenance.
Optional Machining for Temperature Sending Unit
Optionally, PML can drill and tap a 1/8 NPT hole for a temperature sending unit. This would be for an aftermarket temperature gage. There is a custom machining charge.
PML designed two locations for adding a hole for a temperature sending unit, one on the passenger/right side and one on the driver/left side. Select the option before adding pan to cart. A plug for the hole is included.
The standard size is 1/8 NPT. Check your aftermarket gage to verify the thread specifications for the sending unit before ordering. Call or email if you need a different size.
