Ok, I'm developing a ritual here where every-time I bring my car out of winter or summer storage, I have shifting problems.

I'll investigate and figure out the problem (this time around I can't find 1st or 4th), but I'm curious, does everybody have to tweak their shifting often, or is it suppose to be set it then forget it for couple years?

I have had a 2nd gear problem soon after I bought the car (it grinds when cold, but works great once heated up, I skip it when cold), so I don't know if it's a cancer slowly spreading on the inside or just finicky shifting.

Somethings up, you shouldn't be touching the adjustments.

Start with the norm's like shifter bushings just to get a good point of condition.

Next I'd start looking into the motor and tranny mounts. They are probably allowing the whole power train to move around a little.

I've replaced many over the years. Makes a big difference, even when the old mounts "looked" okay. 40+ year old rubber just doesn't work as well as new rubber.

And don't forget to check the cone setscrews ...

Yup, that's what it was. Apparently the little silicone (or whatever it is) that comes on new cone screws doesn't work worth a crap. It was 75% unscrewed, and I had just replaced it in Nov. and it has sat the past 2 months.

Just another thing to keep my eye on! No big deal, I'm use to the seasonal shift linkage problem by now.

The original screws have no silly-cone ... They have a metal tab inside the thread that deforms when used... They should not be reused ...

Have you checked/changed the oil in the box?

Metal? I thought they had a nub of nylon sticking out the side...

--DD

They do have a nylock nub. One use.

I have seen and used quite a few with metal in the threads, not nylon ...

Are these screws on the shift linkages for all years or is it an early vs late deal? It has been over a year since I pulled my motor and I know I am getting old, but I sure dont remember having to undo one of these to remove the linkage in my '72.

Scott you are just getting old!

There's a cone set screw at both ends of the shift rod. One goes in the coupler with the nylon bushings at the firewall (forward end of the rod), and the other goes into the ball cup fitting that goes on the rear end of the shift rod.

In a pinch a small drop of the low strength thread locker will work until you get a new set screw. There are also cheapo repro's that don't have the nylon locking nub in them, worth paying a few cents more to get them from Porsche.
