I won't get into the "filled for life" debate other than to say it's not for me.

So what procedure would you use to set the level correctly? Walk with me through this:
1. Remove fill plug.
2. Remove ATF oil pan (+ filter) which drains the ATF fluid.
3. Install new ATF oil pan (+ filter).
4. Fill with new ATF fluid (ZF Lifeguard 8) into the fill plug hole. The new ATF fluid would be room temperature at this point. Fill until it reaches fill plug hole?
...here's where I'm in need of a lot of clarification.
You'll have to bring the new fluid up to the specified temperature range at this point. ATF fluid is expected to expand so if you filled to the fill plug hole at room temperature, you would expect some fluid to flow out of the fill plug hole at 40-50C.
