Major bang for the buck--shifter rebuild
I just completed a rebuild of the shifter mechanism in my 70 911 (901 trany).
What a difference!!!!!!!!!!!!!!! Of all of the maintenance I've done on this car, this process provided the most improvement of driveability for the least amount of money and time. The rear bushings finally gave out last week so shifting became a challange. It forced me to do the repair. Like the frog in the pot parable, the degredation in the shifting was so gradual that I really didn't notice until the rear bushings broke up. Anyone with more than a couple of inches of play in their shifter should consider this cheap and easy process. The parts are cheap ($20-30) and the process is not real difficult. On inspection, the shift plate was worn so I changed it out as well. That was the toughest part 'cus of the springs. If you do the shift plate, I can help with the process. I remembered a posting by another Porsche guy about this, but I can't remember his name. It was extremely helpful. If you have any doubts, go for it. OK, I've rambled enough. Going back to my Corona now. Rob Rob

Rebuild the shifter and coupler along with the replacement of the shift rod bushing makes a world of difference.

The manual says that free play in all gear positions should be similar side to side and front to rear. After replacing all 4 bushings, 2 in front and 2 in the shift coupler, my free play is about 1 - 1.5 inches in all directions.

BTW, "free play" usually means the distance a part moves before anything significant happens. For a shift housing assembly, 1-1.5" is either excessive or needs redefining. Sherwood |

Did mine when I bought it 7 years ago. Major improvement, did it in a morning, not knowing what I was doing, other than Wayne's book.
