If you did a complete exchange that sounds about right since the stock capacity is 11.5. If you did a drain and fill you can get 4-6 Quarts out depending if you lift the left (passenger) front in the air. If you did a drain and fill sounds to me you are overfull. Even if you got 6 out it would only take roughly 9 Quarts to fill with the PML pan installed.
