It is interesting that it is only the "forward" gears that you are having trouble with. This may indicate an issue with the shifter alignment. If the shifter is not located properly (i.e. to far back in the throw) you may have trouble engaging the forward gears (R,1,3 & 5) while still being able to reach the back gears (2,4 & 6) There is a special tool (#9619) that Porsche has to lock the shifter in the proper "neutral" position and from what I have heard the dealer can check the alignment of the shifter rather easily with it. You may want to start by comparing the location of your shifter to the realtive position of another 996.

If the shifter checks out then I would start in on checking the cables. Good Luck
