If you are going to change the oil why not flush change the whole content. You can do this by disconnecting the line going to oil heat exchanger. Guiding the fluid from there to a a drain reservoir and filling the oilpan with drill pump or similar while engine running. Dexron III -H is the specs. I've used Petro Canada ATF D3M.
Here are some pictures from 2007 when I did this first time to my E39 530d with the same gearbox. It had a new TC at about 300t km (preventative) and now running 400t km without a problem.

Thanks Clavurion, but that might be a little difficult for me to replace the TC in my garage on my back and certainly no money to have it done. I will just pray to the BMW Gods to have mercy on me and not destroy my transmission because of a clutch surface.
I have seen the Dexron III-H, I think AC Delco offers one. I wonder if I should stay with the non synthetic or move to the synthetic Dexron VI
