We have written several articles about the NAG 1 five-speed automatic transmission used in Dodge, Chrysler and Jeep vehicles. It comes in both two-wheel drive and four-wheel drive configurations and may also be referred to as the WA580, W5A580, 5G-Tronic or 722.6 transmission.

If you have added any type of power adders to your HEMI you should consider the possibility of adding a new Performance NAG1 transmission. Adding a new transmission to your car you will ensure that your powertrain will hold up to the demands placed on it.

What Is A Valve Body?

The valve body is the control center of the automatic transmission. It contains a maze of channels and passages that direct hydraulic fluid to the numerous valves which then activate the appropriate clutch pack or band servo to smoothly shift to the appropriate gear for each driving situation. Each of the many valves in the valve body has a specific purpose and is named for that function. For example the 2-3 shift valve activates the 2nd gear to 3rd gear up-shift or the 3-2 shift timing valve which determines when a downshift should occur.The most important valve, and the one that you have direct control over is the manual valve. The manual valve is directly connected to the gear shift handle and covers and uncovers various passages depending on what position the gear shift is placed in. When you place the gear shift in Drive, for instance, the manual valve directs fluid to the clutch pack(s) that activates 1st gear. It also sets up to monitor vehicle speed and throttle position so that it can determine the optimal time and the force for the 1 - 2 shift. On computer controlled transmissions, you will also have electrical solenoids that are mounted in the valve body to direct fluid to the appropriate clutch packs or bands under computer control to more precisely control shift points.
