Actually they are very different. The 4R70W (out of the box) can handle more torque than an AOD-E. As stated before and well known, the gearing is different.
The output shaft on the 4R70W is stronger, than on the AOD-E. In 1998, the 4R70W started using the Mechanical Diode Intermediate One-Way roller clutch. The AOD-E does not have this feature unless it was rebuilt and/or overhauled. The MD OWC is virtually indestructable. The standard OWC (sprag like clutch) fails often.
Sure these parts can all be put into an AOD-E case, but that's not what I'm talking about.
It really doesn't matter much how you want to argue it. The MN12 never had an
AOD-E during a production run.
