Gearbox problem
Hello All,
I have a problem with my gearbox ( type 915 - Porsche911 SC 1982 ) During a ride through the city, I can change all the gears without any problem, but when I drive on the highway and stay for longer time in fifth gear, it is very difficult to return to 4th gear. I must pull very hard on the lever. Has anyone any experience with this problem? Kind regards, Jan |

I´ve heard of this problem before on 915 boxes. Its apparently a worn hub catching the shift sleeve.

notched (worn) 5th/reverse hub is the usual problem. seen some pretty bad ones.

I could never drop from 5th to 4th, I always have to bring the shifter up to third, then down to 4th.

Since we're on the subject of 5th gear issues, how about this:
I have a difficult time finding 5th. Sometimes the shift goes smoothly, but last weekend the shifter got stuck in 5th. I was able to yank it back down to 4th - pausing in neutral first, of course - but don't want to repeat the experience. Recently replaced pedal bushings, shifter bushings, shift cable, and helper spring. Clutch action is great and synchros seem good other than first gear being a bit balky from time to time. Synchros replaced about 25K miles ago, long before I bought the car. Worn hub?
