“NAG1” refers to a category of automatic transmissions that features a round 13-way connector located near the right side, front corner of the transmission oil pad. The “N” stands for “New”, the “A” stands for “Automatic”, and the “G” stands for “Gearbox”. The number “1” represents the generation, which in this case is generation 1.

Sometimes, you will notice that NAG1 transmissions will be referenced by other names, such as WA580 or W5A580. These “marketing” names can be interpreted in the following manner:

  • W = A transmission using a hydraulic torque converter.
  • 5 = 5 forward gears.
  • A = Automatic transmission.
  • 580 = Maximum input torque capacity, rated in Newton meters.

NAG1 Top Features

The NAG1 transmission features an electronically controlled 5-speed transmission system with a lock-up clutch that is located in the torque converter. NAG1 gears are activated hydraulically using the electronic controls. The automatic trans is found in many Chrysler products, including Grand Cherokees, Dodge Caravans, Ram trucks, and Jeep Wranglers. It’s not exactly clear why the brand made the switch, but one can expect that the electronic controls played a factor.

Top benefits of NAG1 transmissions include:

  • Increased gas mileage.
  • Increased shift control.
  • Increased service life.
  • Lowered maintenance costs.
  • Improved step-ups through the five gears.

Though there were some complaints earlier in the transmission’s lifespan – sensitive to fluid quality, transmission filler tube o-ring leaking, slow shifting – these issues have worked themselves out. In fact, the NAG1 is now praised for its fast shifting capabilities.
