Millers Nano for tranny. Fabulous improvement for my 48,000 mile C4. Expensive but no more so than Porsche brand. I put Millers Nano motor oil in as well.
Purchased on Amazon. $103.

Do you mind listing exactly which ones you use, their website lists many types. Even when you use their "oil guide" it lists several options.

I ended up buying mine from my local Porsche dealership: Checkered Flag Porsche, in Virginia Beach. It worked out to $143 after tax. Suncoast shipping cost would have made it about the same. I changed it yesterday.I am going to see if I notice a difference on the very cold mornings where I was getting stiff shifts for the first 5 minutes of driving.

In my 986 Boxster S I'm going to use CRX 75w90 NT for my next fill, according to Karl at performance racing oils it is the right one for that stock transaxle. I'm also running the CFS 10W50 NT oil on track for HPDE and changing it about every 5000 miles with good UOAs.
