hi,

I'm rebuilding my 5spd transmission, and at the same time I'm considering replacing the front and rear couplings for the shift linkage:

I'm confused. Are my exixting couplings worn or not?

Rear: Took it out today. I'm told it should have some play, but mine is very sloppy in all three axis. But the bushing appears machined this way, and I see no sign of wear. Please advice. I'm also told I can replace just the bushing with a 911 equivalent. I have PET, what year 911 should I look at?

Front: It's still in the car. I can move it significantly up/down, but not fore/aft. Do I replace?

a mechanic friend replaced mine just yesterday and the shift has improved dramaticaly. this is the old part next to the new one, i wouldnt think you could replace just the rubber insert as it sits under a lip. the job was from his account a PITA and took quite some time due to the restricted working space. from my point of reference it was really worth it. what surprises me is that the bush could wear like this after only 79k??

Do a search on "ball cup" the r&r is not difficult using the right technique.....more effort expended getting to the part than replacing it. It should not move up and down at all, that is the symptom of a failed one. The plastic "seal" is what keeps it on the ball, and it is not replaceable. The part is readily available and not terribly expensive.

thanks, I'm getting a new front one, then. My mechanic is making new nylon bushings for the rear one, no more slop here. The local Porsche dealer told me the brand new ones had some play in them too, but it was OK to install a custom made solid one. The only drawback would be less filtration of vibrations from the transmission.
