It made the shifts slightly smoother in my car also. However, I think its the DME that is really limiting improvement in shift times. The fact that this is a 4 speed gearbox is one of the major drawbacks of the 993 tiptronic in my opinion. My fluid was most likely original fill, and was removed at around 76k miles. I found only dust like particulate stuck to the magnets in the bottom of the pan--everything looked good and the ATF did not smell burnt at all.

My best advice to you in order to get the correct fill is to measure what comes out and put that much or just a little more back in. I did not measure with the temp gauge as I did not have one available.
