The 2006 Dodge Charger uses a 5-speed automatic transmission (NAG1/W5A580) paired with its powerful HEMI or V6 engine options. Known for its sporty performance, this transmission handles high torque output well but can develop issues such as torque converter shudder or slipping after high mileage. Regular fluid changes using ATF+4 fluid are critical for longevity. Replacement transmissions for this model range from $1,200 for used units to $2,800 for remanufactured options. When shopping, confirm compatibility with your engine type — V6 and V8 models use different units. A professional installation ensures optimal performance and prevents costly comebacks on your 2006 Charger.
