I am planning on replacing the filter and the container O-ring on my 968 tiptronic, but wondering if I should do a full flush of the trans and replace all the fluid. I've got 88K miles on it and would bet its never been touched or at least not done to schedule. Has anyone done an actual full flush, or does it need it and the filter change fluid replacement is enough?

Will the modern ATF replacement machines work for these units through the radiator if I bring them a new seal?
