Short shift problem

[renos]

I have a Porsche short shift (actually it is not even the very extreme one as mine comes from the 550 anniversary model) on my 986S that presents the following problem when cold. The movement obviously is generally stiff when the system is cold like all SS systems, but if I select reverse when I go back to neutral if I am not very careful with the movement of going from reverse to neutral, the system becomes somehow blocked in the neutral position and I cannot engage any gear as if the stick is locked. I then have to shake the stick with short movements in all directions until it unblocks. When warm no problems are encountered. What I mean is that when I disengage reverse I have to do the movement very slowly and precisely and not instictively like it is the norm in all cars,in order to avoid this nuisance.

What is your opinion? The wires are ok and the clips at the back are well secured. Could it be something inside the gearbox and if yes why only when cold.

Your assistance will be appreciated. Thanks!

Well its normal for the shifting to be notchy and alittle tough when the gear oil in the tranny is cold and at its thickest form with cold. However, Not being able to engage reverse isnt too common. I have a question for you... Are you using any thicker gear oil in your transmission like RedLine or something similar? If so that could be the problem right there because thicker gear oil seem to make shifting when cold more laborious than the Porsche Recommended oils would.

I use the Porsche gearbox oil.

Reverse does engage when cold, the problem is that when I disengage, if I don't take extra care to do a slow accurate movement the whole system blocks , like I mentioned above.

Take a look under the car, aside the transmission is the mechanism for the gear shift located, and is made in two pieces ( one for each cable ). Let a helper in the car actuate the shift lever and watch the mechanism, they can hit each other or the transmission case when bend.
