I can easily promise that I will report back honestly whatever ends up happening.

So far I have only changed approx 2.5 liters of Pentosin ATF 1 and I've added 1 bottle of the blue trans-x. The shifting is much improved. Much improved. I still get the occasional hard shift, but I've only driven it 70 miles since adding the trans-x.

Since the fluid has likely never been changed with 113K on the odometer, and the fluid is black and no longer able to function as it is supposed to, I am going to do the filter service and change another 4 liters of fluid.

My parts just arrived from Pelican and I plan on using my buddies lift to help do the trans service middle-end of this week. I will report back if it is better or destroyed.

I test drove a 2006 and a 2016 Boxster yesterday. I still prefer the smaller feeling 986, though I might sell this one after fixing it up a bit and swap for another 986 "S" with a manual trans since I prefer manual in my sports cars.
