Read about PML NAG1, 722.6 Transmission Pan Design (a new window or tab will open with a PDF file).
Many Chrysler, Dodge, Jeep, and Mercedes vehicles have the NAG1, 722.6 (W5A580, WA580, W5A380, W5J400) transmission so PML has designed three different pans for the transmission.
Some vehicles which typically can use this pan are:
- Jeep Grand Cherokee (SRT8, Laredo, Limited, Overland), 2006 to 2013
- Dodge Magnum, Charger, Challenger, 2006 to 2013, some 2014
- Chrysler 300, 300C with 5 speed transmissions, 2005 to 2012
- Mercedes (several models/years, sound plate may need altering, see INSTALLATIONS)
- Sprinter Vans (some models, usually 2002 to 2006, check for frame crossmembers)
Always check your vehicle to verify transmission and clearance as configurations vary.
See Installations for examples.
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
Some space, like Grand Cherokee, some cars (Magnum, Charger), some Sprinter:
NAG1, 722.6 2 Quarts Over Transmission Pan (this 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.

2015 Jeep Wrangler, Aftermarket Exhaust and Frame
Wes updated his 2015 Wrangler Rubicon with a turbo from Prodigy Performance. An added benefit of the turbo is the space available for this PML deep transmission pan.
Wranglers with the NAG1/722.6 transmission usually use PML stock capacity pan 11132 because the stock frame and exhaust do not allow enough clearance for a deep pan. With the aftermarket turbo, Wes had space for this PML deep transmission pan.
With this PML pan installed, Wes reported to us that his fluid temperatures are consistently 12 degrees cooler than before.

2013 Jeep Grand Cherokee SRT8
Randall reported that his transmission fluid was 190 degrees after 30 min of driving before installing this PML pan. After he installed the PML pan and driving for 30 minutes with the temp outside at 90 degrees the fluid temperature was at 170 degrees. He removed about 4 quarts and added 1.3 gallons plus half a quart. He purchased a Dorman NAG1 transmission level dipstick from O'Reillys so he could check his fluid level.
For the filter, Randall suggests checking that the o–ring from the old filter is removed and that the new filter seats correctly in the slot in the valve body (see image at left).
He did not have any clearance issues from the larger PML transmission pan. It cleared the frame, exhaust and skid plate.

2010 Jeep Grand Cherokee SRT8
Troy installed this pan on his 2010 Jeep Grand Cherokee SRT8. The design of the Jeep makes for a close fit and the passenger side bolts were difficult to reach and he recommends a long allen head sockets. He reported about 0.300 inch clearance between the PML pan and the catalytic converter. From the exhaust hanger to the PML pan, he has 0.070 inches. He removed 5.5 quarts and added 8 quarts. He used RTV. No leaks and shifting is good.
Troy took fluid temperatures using the Torque Pro app and reading the PIDS input from the transmission directly. He saw about an 8 degree F lower termpature in daily driving and the extra capacity takes a little longer to get hot, which is perfect for his racing.

2007 Grand Cherokee 3.0 Diesel
Robert installed PML's deep pan for the NAG1/722.6 transmission on his 2007 Jeep Grand Cherokee with the 3.0 diesel engine. He is very happy with his PML Pan and reported that "The directions were well written and easy to follow. The bolt hole depth check was a very important detail. The fit and finish of the cast pan was excellent. There was tons of room for the pan to clear the exhaust and drive train." He added 1.75 quarts more than stock. Our thanks to Robert for email us his pictures and comments.

2006 Jeep Grand Cherokee
HGM Transmission Controllers installed PML's 722.6/NAG1 transmission pan on a 2006 Jeep Grand Cherokee Laredo V6 3.7L. The installation was a simple bolt-on process. Even thought this is a deep pan, the exhaust and frame are still much closer to the ground than the pan so there are not any clearance issues. Our thanks to HGM for installing our pan.

2006 Dodge Magnum SRT8
Stefan installed the PML deep pan for NAG1/722.6 transmission on his 2006 Dodge Magnum SRT 8. Here is a link to more pictures posted on Facebook: PML Pan on Dodge Magnum. He had these notes on the installation:
- Removed the cross member for access to the two rear bolts
- Used Chrysler AT RTV to seal the pan to the transmission
- Cross member fit with the PML pan, no clearance issues
- Stock fluid was 4.8 quarts, added 1.7 more quarts with PML pan for a total of 6.5 quarts
- Used chart to get accurate read for fluid level at a temperature (chart found on-line or in Hanes manual) while car in reverse or drive
- A special dipstick is needed (can be ordered at dealership, local parts store or Amazon)
- Drain plug in the rear works well
Our thanks to Stefan for his comments and pictures.

2005 Mercedes Sprinter 3500
Jon, a mechnical engineer and designer for Whitledge Designs, noticed his van, "The Magic Bus", struggled over long grades and fluid temperatures would rise.
He performed a number of aerodynamic and thermodynamic calculations, and estimated his Sprinter required an additional 49 horsepower to climb the Cajon Pass (California) at 60 mph. This translates to the dissipation of about 125,000 BTU/hr of additional heat (note: one horsepower equates to 2544 BTU/hr). After weeks of research and fabrication, he developed auxiliary cooling systems for the radiator and transmission and included this PML pan as part of his plan.

Mercedes C55
Damian installed this PML deep 722.6/NAG1 transmission pan on a 2005 Mercedes AMG Class C55. The pan installed easily, fit great and did not reduce overall ground clearance. The PML pan does not allow for the undercarriage sound dampening plate to mount as designed so he cut out the bottom of the plate below the pan. This also aids with air flow and cooling. Although the PML pan is too deep to not hit the plate, the exhaust hangs down further than the PML pan. Our thanks to Damian for the pictures and comments.

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.
First image: inside of PML pan showing filter supports
Second image: stock filter
The Mercedes part number on the filter PML used during design and development is 140 277 00 95.
PML design this pan to work with the stock filter. There are filter supports cast into the pan to hold the filter in place at the same level as the stock pan. The filter supports eliminate the need for an extension.
Dipstick and Transmission Fluid Level
The fluid level should be at the same level in the stock pan and a PML pan. The correct fluid level may be based on temperature.
On many vehicles, the dipstick uses the bottom of the pan as a stop. PML pans have a ledge where the dipstick hits at the same level as the stock pan even though the PML pan is larger overall. In the above image of the inside of the pan, the square ledge is next to the pan wall between two boltholes. In the image below the recessed square area is the location of the ledge where the dipstick would hit.

Some vehicles with these transmissions do not have a dipstick. 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. PML does not provide a dipstick.
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. If you have an older pan, you will need to fabricate a connector or slightly bend the shield to bolt onto the PML pan.

Drain
Click on image to view larger.
PML placed the drain hole on the driver's side, near the rear of the vehicle. A side location for the drain is safer than the bottom and still has easy access. A magnetic drain plug is included along with new mounting bolts.
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 three locations for adding a hole for a temperature sending unit:
- Driver/left side
- Passenger/right side, toward the front
- Passenger/right side, toward the rear
Click on image to view larger.
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.
