Thanks Phil.
I went to bavauto's web site, and put in a 4.4 and looked at the tranny fluid capacity, and it stated 6.0 liters. When I changed to the 4.6, is showed 6.2 liters. Go figure.
Now I did leave the tranny pan off for over a week with a catch pan below it, and it dip continue to drip oil for days, but I'm pretty sure it didn't drip 0.8 liters worth!
I would have thought the oil in the torque converter would be stuck there unless sucked out by force.
Drive it to work this morning, and everything appears fine. Never did have an issue before, but at 134k, I figured it was time (I only just purchased the car in the spring with 133k on it and have been fixing it up).
