Transmission problem with 2nd/4th gear selection, why does this happen right before a track day!!!! Options

Hello, I could use a little input on this one.

So less than 11 days to a non-refundable track day at Thunderhill and my tranny won't go into 2nd or 4th. I have disconnected the linkage and cannot engage 2nd or 4th manually. 1st, reverse, 3rd and 5th are fine. It's like there is not enough throw at the side shifter input dongle. It also seems to require a lot of throw to get 3rd/5th engaged to the point that the ball is starting to pull the bushing out of the socket.

Its a 914-6 transmission rebuilt and converted to side shifter by a local Porsche "specialist". About 9 years ago. My tranny has never shifted right since the rebuild and I kept telling myself it was the linkage or something else. Now the problem has presented itself completely! 4th was always "soft" but now its not there at all and 2nd has joined the party. No grinding just no engagement. The car was in project stage for long after the work was done so it tough to try to bring it back to the specialist.

Got any ideas, Is there anything I can adjust with the tranny in the car or should I pull immediately and try to figure it out. I have rebuilt Porsche engines but always stayed out of the transmission world.

thanks Daron
