Sounds about right. My two recent drain and fills were about 4.5l (a bit over 4.5qts) but in both drain I left it overnight (drain while hot - leave overnight to get cold before fill and then warm to correct temp to set level).

Two drain fill cycles will replace about 75% of the fluid.

Sadly, I now have a trans problem... it has developed a 5th slam at low loads (around 1500rpm or so) - this seems to be a direct result of the drain and fill.

Thinking about options - most likley is a mechatronic "rebuild" such as you are doing.
