You can easily rotate the engine using the power steering pump... With the engine shut off rotate the power steering unit clockwise(engine always needs to rotate clockwise) until you can see the allen head drain plug in the torque convertor. Yes all the fluid needs to be drained because it is now mixed... You need to be under the torque convertor and while looking up have some one rotate the power steering pump.. Really quite simple.
