Does anyone know if all the different engines for the charger use the same transmission? I realize it's always the A580, but does it always use the same parts? Coming from GM, the 4L60e transmission came in 2 flavors, and had different torque ratings. I was just wondering if anyone knew if the same holds true for Dodge, or are all the trannies identical? I haven't been able to make much sense of the Dodge website yet.
