Planning to drain the ATM, disconnect the 
inlet to the oil cooler and blow remaining oil in the cooler back into the pan with a gentle push from an air compressor. 
Then fill the pan with clean oil, start the engine for a couple of minutes only and pump out old oil remaining in torque converter etc into a bucket while using drill pump to replenish until am sure the new oil is coming through into bucket. Stop engine and drain pan again then remove pan, clean it and replace filter, replace pan and refill. Reconnect oil cooler, start engine and keep refilling until begins to drip as per RAVE. 
Apparently one needs to keep filling and then close up filler hole while engine is running. If you stop the engine a lot of oil will flow back and you lose it through the filler hole... then the levels are all wrong... Also the fluid has to be between 20 and 40 deg C, otherwise it expands significantly and the transmission is sensitive to correct oil levels...
Changing the filter last is because the filter is at its most efficient when its partly clogged

.
Well that's the theory anyway!
WRT the TF case, just drain it for 30 mins or so when it's at ambient temp. Refill until it begins to dribble from the filler hole. all done!
