I guess, taking your earlier advise I will keep my old 12k trans oil sump for another 30-40K's before replacing it and only change the oil. Also, wit the pan on, only 4 litres of oil drained, when I took the pan off, another 1.5 litres of oil drained. So a total of 5.5L with taking the pan off, otherwise only 4L would have come out. Now the pan is hanging on the car while I get new bolts tomorrow, do you think I should still do a 2 drain process suggested earlier or just one?

I don't think I want to remove the mechatronics unit yet on my car, and I do have a new sealing sleeve, if anyone wants to buy that within Australia .
If your objective is to run fresh fluid then yes you should drain and fill twice.
Doing it twice will mean you will have 85-90% new fluid.
