The NAG1 transmission, also known as the W5A580, is a 5-speed automatic transmission widely used in Dodge Charger, Jeep Grand Cherokee, Chrysler 300, and even some Mercedes-Benz models. Designed for smooth operation and efficiency, the NAG1 is electronically controlled and built to handle modern driving demands.
NAG1 fitment is application and generation specific. The Chrysler 300/Charger/Challenger application differs from the Jeep Grand Cherokee WK application in output shaft configuration and shift calibration. Within Chrysler applications, the HEMI and V6 variants use different torque converter specifications. Our VIN verification process confirms the exact NAG1 variant — including engine pairing, torque converter spec, and RWD or AWD output configuration — before your unit ships.
When the NAG1 needs replacing, vehicle owners face a choice between a costly rebuild at a ZF-certified specialist rate, or choosing a used transmission that restores factory performance immediately. Choosing a used NAG1 transmission is the most cost-effective path — whether you call it a used transmission, a low-mileage OEM transmission, or simply the right replacement — a used OEM NAG1 gives you factory Mercedes-Benz engineering at a known price. Unlike a remanufactured transmission assembled from mixed components, our used OEM transmission is a complete factory unit that restores the smooth, precise shifting your vehicle was built to deliver.
Every used NAG1 transmission ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included, but we can help you find a qualified Chrysler or Mercedes transmission specialist. These are genuine OEM units, and we stand behind every one.
