Automatic transmission P52108480AK 4×4 5.7 HEMI V8 DODGE CHARGER 43TKM

at Buy Mustang parts Ltd, the part number P52108480AK refers to the 5-speed automatic transmission specifically for the AWD (4×4) Dodge Charger equipped with the 5.7L HEMI V8.

This is the legendary NAG1 (W5A580) transmission. At just 43,000 km (43TKM), this is an exceptionally rare, “collector-grade” mechanical unit.

1. Technical Identification

The NAG1 was originally a Mercedes-Benz design used in high-torque applications (E-Class, S-Class) before being adopted for the Chrysler LX platform.

• Model: NAG1 / W5A580

• Drivetrain: AWD (All-Wheel Drive). Note that the output shaft and housing for the AWD version are different from the RWD version; they are not interchangeable.

• Torque Capacity: Engineered to handle up to 580 Nm (428 lb-ft), making it a perfect match for the 5.7L HEMI.

• Gearing: 5-Speed with Adaptive Electronic Control.

2. Condition & Inspection for Buy Mustang parts Ltd

A unit with only 43,000 km is a “plug-and-play” asset, but for luxury resale, you should verify these three specific NAG1 pain points:

1. The “13-Pin Connector”: The electrical plug on the passenger side is notorious for leaking ATF. Even at low mileage, the O-rings can dry out. Replacing this with a new Mopar #68021352AA adapter plug is a $15 part that prevents a $2,000 failure.

2. AWD Transfer Case Interface: Check the rear output splines that mate to the transfer case. Ensure they are free of rust and that the seal is pristine.

3. Conductor Plate: At 43,000 km, the speed sensors on the internal conductor plate should be perfect. However, if the car sat for a long time, ensure there is no “varnishing” from old fluid.
