OK, I'm stuck.

I'm trying to replace the little white plastic cup that the stick sits in (1980 5-speed). Everything came apart OK, got the stick mount off the torque tube, got the old cup off the stick. When I tried to mount the stick onto the new plastic cup, the little plastic cup shattered! Very annoying.

Is there some trick to doing this? I am going to order a few new plastic mounting cups from the dealer, but I'd like some advice on how this is done before I try again...

I've always removed the stick by prying it up out of the mount. The mount and the plastic piece were left attached to the torque tube. Then to replace the stick, I pound it down with a hammer and short piece of rebar. I don't know - maybe the plastic is supported better and stays together because it's left in the mount for re-attachment to the stick?
Anyway, if you have to connect the plastic piece and stick out of the car, you could boil a cup of water, drop the plastic piece in for a minute or so to make it somewhat pliable and less brittle, then attach it to the stick.

I guess there is no reason I have to attach it together out of the car. You are probably right that when left in the car, with the support around it, it is less likely to break. I will try that. I ordered 2 more and they will be at the dealership this week, so I will try again on the weekend with the whole assembly in the car.

Could you explain "I pound it down with a hammer and short piece of rebar" a little more? Can I just hammer on the top of the stick (knob removed of course) to get it in place? What does the rebar do?

I did the Operation Shifter Egg as described in those pictures, now it feels like a car again, thanks Smoothie.

But how you remove the shifter with the mount still attached to the torque tube is beyond my understanding. I tried it with some large screwdriver and other stuff, but I was afraid of breaking them, the shifter didn't move. Btw Haynes writes the same for removing the shifter. Then I've found that the mounting can be removed, and it was Ok after.

'80 924 4-speed, if it makes a difference.

Thanks, great picture! OK, I will try that as soon as I get the new "cups"...

That is a bit tough, but I found if you slip something under the shifter at the bottom (a piece of metal of the correct thickness like a large nut, a bolt or whatever), you can then tilt the shifter toward the metal piece to pop it out.

OK, all done, what an improvement!!! It got rid of a fair amount of "looseness" and my shifter no longer makes an awfull rattle at high rpms.

I used the advice given here, I installed the cup and the mount first. Then I took a BBQ lighter and gently heated the cup. With one swift hit to the top of the shifter with the hammer, the ball slipped into the cup no problem.

Everyone should replace their shift rod and support cup, the improvement is worth it for the $50 it will cost you...

Looseness as in side to side, or front to back on the shifter? Mine is terribly loose side to side, as far as the throw from 3rd to 4th. But front to back its real tight.

Replacing that pin on the shifter (either by replacing with a new shifter or by replacing just the pin with a bolt as teo and I did) - improves both front-back and side-side movement, but it does have more of an affect on the side-to-side. The pin wears to an egg-shape - at the center it remains -relatively- unworn or much less worn than at the two ends, so front-back motion is less affected. The side-to-side motion of the stick translates to a twisting motion on the long rod that reaches back to the transmission and as the pin becomes egg-shaped, you're left with more side-to-side slop. Look here - http://pg.photos.yahoo.com/ph/smoothies931pics/detail?.dir=/a174&.dnm=2921.jpg&.src=ph
In my case, there was not only slop, but it also wouldn't reliably go into reverse - reverse being to the far right and back on the Audi 5-speed. The shifters' movement would be limited by the side of the opening that's cut for it in the center tunnel and with the amount of wear I had on the pin, I'd hit the side of that opening before the rod going back was twisted enough to line up for reverse. -So, I could expect to have to try several times before being successful each time I had to put it into reverse. With the pin replaced now, it goes right into R on the first try.
