Applications

This PML transmission pan fits the 722.6/NAG1 (W5A580, WA580, W5A380, W5J400) transmission.

PML designed this 722.6/NAG1 pan for vehicles that did not have clearance 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.

This pan is available in two finishes. Learn more about finishes and construction of PML parts.

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

PML makes three pans for the NAG1/722.6 transmission. Need help figuring out which pan you need? Check out this video or see our NAG1/722.6 Transmission Guide for help.

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. 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 for PML 722.6/NAG1 Low Profile Transmission Pan

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.

Locations for Optional Temperature Sending Unit Machining

This pan can be drilled and tapped for a temperature sending unit. There are locations on the driver's side and the passenger's side of the pan. In the above picture, see the round, cylindrical shaped features. These areas can be drilled and tapped to specifications from 1/8 NPT to 1/2 NPT.

PML has a machine shop in the building and can drill and tap to your specification for $45 per hole. Machining usually takes about a day.

Installations

Many thanks for these images and for selecting PML transmission pans.

• 2014 Wrangler W5A580

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:

1. Stock pan, rusted and distorted from retaining clips
2. 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.
3. Brake cleaner used to make sure surfaces and drain plug were clean of any bits.
4. 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.
5. A floor jack is needed to re-install the cross-member.
6. 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.
