Sloppy SC Shifter question
Hi
My 81 SC has a pretty sloppy shifter. The lever will move almost an inch side to side while in a gear. Also, there is no spring in neutral. I have heard that the bushings are probably worn. Which bushings are these most likely to be and how difficult are they to change? I pulled the shift boot up and can't see how you get the large inverted metal cup off to get in there to the shift likage.
Thanks for any help.

Greg,
If you remove the floor carpet behind the driver/passenger seats, on the floor you'll find a metal cover with 4 screws. Take it off and you'll find the shift rod coupling which joins the transmission to the shift lever assembly. Put your shifter in gear and rock it back and forth in the way it bothers you. Chances are good you'll see the slop in the assembly. That assembly can be refreshed by replacing the bushings (Weltmeister is a brand) or buying the complete joint (Weltmeister brand, and Porsche, 911.424.024.04, both around $60).
Another part that can contribute to slop is the plastic cup the shifter itself sits in. This is available from Porsche, 911.424.139.00, and Weltmeister.
Removal of the shift tower entails removing the front console then undoing several bolts at the shift towers base.

ditto above. When I bought my SC the shift was real bad, now it is just fair.
But the shift coupler has a set screw, mine was loose , very loose. I tightened the set + replaced the shifter bushings, it helped alot. But I still think my SC has a very poor shift charactoristics!!!!!

Pelicanparts.com has an excellent article on how to install a Short shift kit and replace your bushings, it is easy and all the parts you need are avaiable from Pelican or Performance Products.I did this on my 83SC and along with adding Swepco tranny fluid,it made a world of difference! Have fun and Good Luck with it !

I would recommend against any short shift kit except a Porsche factory one.
I've removed several aftermarket units due to owner dissatisfaction.
Also, GPR sells coupler bushings, they're not expensive or very hard to install if you do it right. First remove the coupler, then pound the pin out while supporting the housing, replace the bushings, grease them and the pin, then pound the pin back in. Take special care to re-install the splined shaft the same way it came out or else the set screw won't have a recess to sit in. Also, NEVER remove the coupler without marking it's position in the shift shaft. I just punch a small dimple in the splined shaft right at the groove in the shift shaft BEFORE I loosen the pinch bolt. GPR's # is (805)549-8525

I recently bought the aforementioned bushings and am hoping this will tighten things up on my '83 SC Cab. The difficult shift is from 1st to 2nd and back again. In fact, going from 2nd to first requires that the car be nearly stopped or gears grind. Am I in for some deeper transmission work or could this just be the bushing and adjustments? This is also my first 911, is there a way to tell if a short shift kit is already installed without removing the console?

Greg,
The only way I can think of to tell if you have a short shift kit in your car without removing the console is to find another 915 tranny car possibly 80-83,but the 915 was used from 72-86.The throw length is what you are looking for,long throw from first to second is normal, short throw is.... short shift kit,although, there is not that much different,you still can tell if you shift one car and go to another and shift it.If you go though the coupler adjustment and the hard second is not any better you could have worn syncros and you would need a tranny rebuild.Peilcanparts.com has an article in the tech section for this adjustment.Hope this helps and good luck !!

Greg,
The Porsche short shift kit can be identified by a raised ring about an inch below the shift **** on the shift lever. A stock 911SC shift lever is smooth from the **** to within the shift tower.
