PML designed this 722.6/NAG1 transmission pans for:
- Cooling — extra capacity on deep models, fins, and aluminum construction for reported temperature drops of 10 to 35 degrees
- Clearance — deep middle to clear cross members on 2007 and newer models
- Drain plug — on the side of the pan 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.

PML designed our deep middle NAG1, 722.6 (W5A580, WA580, W5A380, W5J400) transmission pan for:
- Sprinter Vans, 2500 and 3500 with the W5A380 transmission, 2002 to 2013
- Sprinter Vans (Mercedes), 2500 and 3500, 3.0 diesel with 722.6, 2WD, 2010 to 2017, maybe 2018
- Some Jeep, Dodge, Chrysler, and Mercedes vehicles with 722.6/NAG1, depending on clearance available on vehicle
Always check your vehicle before ordering to verify set up and clearance.
From about 2002 to 2013 Dodge, Mercedes and Freightliner all made Sprinter Vans with the W5A380 transmission. 2007 and newer models have cross members running across the rear and front of the stock pan. PML put a step in the front and rear of the pan to clear these frame cross members.
NCV3 Sprinters: 2007 to 2013 NCV3 Sprinters usually have cross members below the stock pan and will need this pan with the steps in the front and back for clearance.
Sprinter with Winnebago: The Sprinter cab and chassis is used under many Winnebago models, such as View and Navion. This pan has been installed on several of these.
HWH Leveling System: Although we have had this pan installed on vehicles with the hydraulic jack system by HWH for leveling, it is a close fit. Here are reports from our customers:
- One customer reported that the leveling kit is toward the rear of the rear cross member and does not create any additional clearance issues.
- One customer with a 2006 Sprinter 2007 View reported that the front leveler brace had to be modified to allow the pan to fit and he provided details. See INSTALLATIONS.
- One customer reported that the HWH brace is slightly in the way to install the pan. He used a hydraulic jack to push the transmission up a little to gain enough room to work.
4WD Sprinters: The drive shaft may be too close to the pan. PML pans have thick walls. Jason tried to intall this PML pan on his 2015 Mercedes 3500 Diesel Sprinter 4WD and the side of the pan hit the drive shaft. 4WD models with drive shaft interference can see PML stock capacity pan, which has a finned bottom for cooling and an improved sealing surface.
Freightliner Sprinters: Check carefully for clearance to frame cross members. A 2010 Freightliner Sprinter 2WD 3.0 diesel did not have any extra space. PML pans are 0.150 inch larger because of the thick walls.
Installation Note: Many customers have reported back that to remove the stock pan and install the PML pan, they had to support and jack up the transmission and then drop the frame cross member.
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.
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:
- Ground (the transmission pan should not be lower than the frame)
- Skid or sound dampening plates
- Drive Shaft
- 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
Lots of ground clearance, like Sprinter:
NAG1, 722.6 2.5 Quarts Over Transmission Pan (this pan)
These are GENERAL guidelines. PML cannot tell which pan will work since vehicle configurations vary.
We appreciate all those folks that email us about their installations and send us pictures. Many thanks for these images and for selecting PML transmission pans!

2013 Sprinter 2014 Winnebago View
Larry installed this PML transmission pan on his 2014 Winnebago View which was built on a 2013 Sprinter. He thought other Sprinter owners might find it helpful to see how he supported and raised the transmission before dropping the frame cross member.
2011 Sprinter 3500 Van 3.0 Diesel
This PML pan was installed on a 2011 Sprinter 3500 3.0 Diesel. It nicely cleared both frame cross members.

2008 Jeep Grand Cherokee SRT8 (Required Exhaust Modification)
Bill installed this PML NAG1/722.6 pan on his 2008 Jeep Grand Cherokee SRT8. He had to slightly modify the exhaust for the deep middle part of the pan. Bill provided two PDF files with information about his installation:
This Grand Cherokee also has a PML SRT8 differential cover.
Our thanks to Bill for the many pictures he took before, during and after the installation and his feedback. Bill and his mechanic agreed the installation turned our really well.
2006 Sprinter, Winnebago Navion 23H
Jonathan Dwight in Washington installed this transmission pan on his 2006 Dodge Sprinter Navion 23 H with Mercedes 5 cyl. diesel engine and transmission.
The bell housing has humps which hang down. These humps are on 2006 and older Sprinters. PML and Jonathan worked together to make sure the PML pan fit without any interference.
2006 Sprinter, 2007 Winnebago View, HWH Leveling System
Dan installed this PML transmission pan on his 2007 View, floorplan H, built on a 2006 Sprinter chassis 2.7L Turbodiesel. He had the HWH levelers installed and needed to modify it to allow the pan to fit.
Dan had a respected HWH installer do the modification. They cut the center section of the "U" channel cross-brace out and welded in a 1/4" plate metal piece to bridge the span and allow clearance for the pan to be removed. The brace has several saddles across the corners to give it some 3-D rigidity with the attachment. The brace is attached to the frame rails at the same location that HWH installed it.

2006 Sprinter, 2007 Winnebago View Coach
Charles in Georgia emailed us about his installation of this PML transmission pan on his 2006 Dodge Sprinter cab/chassis with a 2007 Winnebago View coach on it. This is a T1N Sprinter with the 5 cylinder diesel.
Charles used Mopar sealant (no gasket) and cut the heads of some long 6mm screws to use as alignment pins to make the installation easier. The Mopar and screws are shown in the picture below. Charles installed a transmission fluid temperature gauge and sending unit in the PML pan. PML machined the pan for the temperature sending unit on the driver's side, toward the front. The drain plug is towards the rear.
Charles let us know about some small humps on the bell housing that hit the front of the pan. These humps are only on certain models. Charles filed off a little material from the front edge of the pan and everything fit fine. PML has adjusted our pan so no modification is needed on future installations (reported to PML on April 2017, fixed June 2017).
2006 Mercedes Benz T1N Sprinter Chassis, 2007 View 23J, W5A380 Transmission
Roger installed this pan on his 2007 Winnebago View coach in June 2017. He does not have a leveling system. This is a T1N Sprinter with the 5 cylinder diesel and bell housing "humps" and W5A380 . Our pan bolted on without any issue. Here are his comments:
Excellent instructions and illustrations. Installed with your gasket using center bolts first to center gasket and pan. Did not really pay attention to front where it abuts bell housing but slowly, progressively snugged up all 6 bolts in crisscross pattern. Pan and gasket aligned PERFECTLY. Torqued progressively to 90in.lbs and all is good. Looks too purdy to be under the vehicle and out of site.

PML makes a cork composite gasket for PML NAG1/722.6 transmission pans.
One PML gasket is included with each transmission pan. Additional gaskets are available.
PML NAG1/722.6 pans are not compatible with the stock gaskets. The PML gasket is not compatible with the stock pan.
RTV can be used in place of the gasket but the pan is designed to work with the gasket.
You can add a second gasket to your order in the shopping cart. If you need additional gaskets after ordering the pan, please call PML to order at 310-671-4345
In this video, learn how this PML pan seals to the transmission housing:
PML includes mounting bolts, magnetic drain plug, and instructions with the pan. A gasket is added to the box for those who ordered a gasket.

Filter for PML 722.6/NAG1 Transmission Pan
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. There are filter supports cast into the bottom of 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. 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, you can see the square ledge near the filter supports.
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.
PML added a tab for the shield to bolt on to in July 2018. For pans without the tab, you might need to fabricate a connector or slightly bend the shield to bolt onto the PML pan.
Drain for PML 722.6/NAG1 Deep Middle Transmission Pan
PML placed the drain hole on the driver's side, near the rear of the vehicle for part number 11124 (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, this pan can be machined for a temperature sending unit.
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.
PML designed two locations for optional drilling and tapping, one on the passenger/right side and one on the driver/left side.
