Applications:

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.

Gasket

PML makes a cork composite gasket for PML NAG1/722.6 transmission pans.

One PML gasket is included with each transmission pan. For additional gaskets, order from this web page: PML 722.6, NAG1 Gasket

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.

Filter for PML 722.6/NAG1 Transmission Pan

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. 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 images 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. 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

PML placed the drain hole on the driver's side, near the rear of the vehicle.

A magnetic drain plug is included along with new mounting bolts.

A side location for the drain is safer than the bottom and still has easy access.

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

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.
