I thought about doing this, but the light available in my garage
prevented me from seeing exactly how much fluid I had removed. I didn't
want to drain it to the point of allowing air into the lower passeges.

That is correct if you're bleeding a system with air in it. But if you
just want to flush the old fluid, there's no need to do anything other
than pull the fluid through the system with a vacuum pump.
