Figured I'd post since I just did this service on my car.

I used an Autologic to completely drain (and then fill) the transmission.

I'd say roughly an extra cup of fluid came out once I activated the pump.

It took pretty much exactly 2.5 liters to fill.

My strainer was absolutely spotless but the fluid was disturbingly dark (25k miles).

Hope this helps.
