Also if you have shifting problems when cold, check the front engine / motor mount. That solved my shifting problems completely. My only problem with 2 gear was that it was not shiftable when gearbox was cold. There are others that report that the 2 gear jumps out. That is the detend problem Gelbster is talking about.

I would recommend the gear oils Porsche recommends, because they have a very special API 4 / 5 composition and additives. In your case with a Box 2000 S Shell Spirax 75W-90 or Mobil Mobilube PTX 75W-90 are the recommended gear box oils by Porsche. I use the Shell Spirax now. Got it from a group buy.
