E63 Transmission fluid...How much do I need..



I would like drop the pan new gasket and just add back the fluid in the pan.
Anyone know how much fluid I need to do this job..07 E63
I was told to use back the fluid I took out since it was new fluid. I dont want to use back that fluid just in case of comtimination.
I will be getting dealer fluid.
Thanks Sunil...
