About Our Remanufactured NAG1 Transmission

At Reman-Transmission, we believe that you deserve access to only the highest quality transmission replacements on the market which is why we are the best place to buy a remanufactured NAG1 transmission or used NAG1 transmission for your vehicle. Don’t waste your time searching for “new NAG1 transmission for sale” when our remanufactured versions are better and more affordable. If you’re looking for a cheaper option, we also have a variety of high quality used NAG1 transmissions for sale.

If you go with a standard refurbished or junkyard NAG1 transmission, you may end up replacing the transmission again in the near future, adding to your overhead expenses. Instead of doing that, trust our professional team to provide you with an outstanding NAG1 transmission at the best price possible. When we remanufacture our transmissions, we take apart the components. Then, we analyze the performance of each individual component, comparing it to the specification set by the original equipment manufacturer (OEM). If we find any issues with that specific part, we replace it with a brand new one from the factory or a fully re-machined equivalent. We also replace every other component in the transmission as to prevent uneven wear and tear that happens with a traditional rebuilt NAG1 transmission. Therefore, it is not unusual for the quality of our remanufactured NAG1 transmissions to exceed new transmissions rolling off the factory assembly line, as we correct any defects during our remanufacturing process as well.

As one of the top supplier options in our industry, we would be happy to provide you with a quality NAG1 transmission for your vehicle. Regardless of whether you have a foreign or domestic vehicle, we are sure we can find a strong remanufactured or used NAG1 transmission for your car or truck. We are so confident in the work that we perform that we provide a warranty on each and everyone of our transmissions including an up to 5-year/ unlimited-mileage warranty on most of the automatic transmissions we sell. If you are looking for the smartest NAG1 transmission replacement option that is the best in the automotive zone, call or email us to speak with a member of our team today!

Our NAG1 transmission Upgrades

A remanufactured and improved torque converter is included with every transmission.

To eliminate the possibility of front seal leaks, vibration, and premature bushing wear, all torque converters are tested for leaks, lock-up, concentricity, and balance.

Every fully remanufactured valve body, with complete system correction and recalibration kit, is tested independently.

All wear-prone valves are restored to stringent specifications and vacuum tested to confirm proper function.

Each remanufactured transmission is hot, cold, load, and simulated road tested using our proprietary CARS (Computer-Aided Road Simulation) dynamometer program.

All remanufactured transmissions are backed by the industry's best, no-hassle nationwide warranty.

NAG1 Frequently Asked Questions

NAG1 History & Information

The NAG1 transmission is found in numerous Chrysler products and has developed a reputation as a durable, reliable, and efficient transmission. The NAG1 is an electronically-controlled 5-speed automatic transmission that includes a hydraulic torque converter and a lock-up clutch. The 5th gear on the NAG1 transmission has been designed to act as an overdrive gear and the ratios on the NAG1 are obtained using three separate planetary gear sets.

The NAG1 transmission falls in the Mercedes-Benz 5G-Tronic class. It was built upon the prior success of the Mercedes-Benz 4G-Tronic class. In the preceding class, numerous transmissions, including the W4A020, the W4A040, and the W4A028 laid the foundation for the success the NAG1 transmission enjoys today. Even though the NAG1 transmission did undergo several upgrades after it was introduced, the NAG1 transmission and Mercedes-Benz 5G-Tronic class as a whole was eventually phased out for the Mercedes-Benz 7G-Tronic class. The NAG1 transmission also goes by numerous other names including the W5A580, the WA580, and the 5G-Tronic NAG1 transmission.

The NAG1 transmission is actually named using an acronym. NAG stands for New Automatic Gearbox (NAG), with the “1” in the name standing for the 1st generation. The alternative names for the NAG1 transmission also act as an acronym. For example, the W5A580 has several parts, where the W stands for hydraulic torque converter transmission, the 5 stands for five separate gears, the A stands for automatic transmission, and the 580 is the highest torque input (in N-M).

The NAG1 transmission is commonly found in a variety of Dodge, Chrysler, Jaguar, Mercedes, Jeep, and Sprinter vehicles. The most popular models that the transmission appeared in were select models of the Dodge Magnum, Dodge Charger, Dodge Nitro, Dodge Challenger, Dodge Durango, Dodge Dodge Sprinter van, Chrysler Crossfire, Chrysler 300, Jeep Grand Cherokee, Jeep Commander, and Jeep Wrangler (JK). Because the NAG1 transmission is an electronic transmission, it comes with electronic controls that allow the gears in the transmission to be activated using hydraulics. In addition, the electronic controls allow for a more precise adaptation of various pressures that have an impact on the efficiency of the transmission itself.

The benefits of this transmission include good gas mileage, long service life, quality shift control, and reduced maintenance expenses when compared to the previous transmission. As a result, it is not unusual to see vehicles that continue to use the NAG1 transmission even to this day. On the other hand, there are a few problems that can arise with the NAG1 transmission from time to time.
