Broken synchro?

Hi all at pelican, been lurking for a while as my 89 2.7 lux has been incredibly reliable up till now, so not felt the need to post.
I was taking advantage of a nice dry day in the uk with some fairly spirited driving. When shifting from 3rd to 4th at about 5k rpm and couldn't get 4th.
Tried 5th ok then could get 4th and 3rd with some dificultey. Tried 2nd and struggled to get the gear then struggled to get it out of 2nd.
I can get all gears when car is stationary, cleanly pulling away and reversing nicely.
I guess the transaxel is toast unless anybody knows otherwise?

I have heard that the 944S Transaxel is stronger would it make a good swap?

Hi this happened to me in my 944S2 in November. Suddenly became really hard to get into gear. Took the car to my mechanic who said the bearings had gone. Only thing to do was rebuild transmission. Transmission is currently at specialist gearbox shop here in New Zealand going through final assembly (yes three months later - parts are hard to get in NZ at reasonable cost so have to import them) and they have advised two of the synchros need replacing as well. Sounds like the same problem as yours . Good luck.

3 months! that sucks.
Will probably get a used unit as they are cheap and fairly easy to get hold of, infact Iwill prob do the clutch while i'm under it and thats the most costly part. did a search and the s tranny has a shorter 5th gear so may not bother as Unleaded is over £1 a litre here so economy is important

Thats the downside in NZ there are only about 24 944S2s in NZ so no one stocks parts for them and the local Porsche agents charge an arm and a leg. Luckily petrol is only about 65p a litre here so economy is not so important to me. After 3 months i just want to drive my car again. Apparently it will be ready at the end of this week.

I have seen physically broken synchros (into 3 pieces) and it will literally "lock you out" of gears as if there is no slot to shift into. I think what you are describing fits that bill.

Cheers for replys guys will try to pull the trans on sat. will open it up and photo it out of curiosty

So pulled the trans out and decided to pull the clutch too as its original. Glad I did as the rubber thing had started to go.
Anybody know if an s2 clutch will fit?

No other clutch will fit with very extensive modifications as the crank/reference sensors read the teeths on the flywheel. Just buy the Sach's spring centered clutch or the centerforce dual friction clutch.

Got my gearbox back all rebuilt and new and same thing happened, My mechanic pulled the clutch to check it and the rubber centre was shot into a million pieces. Had the option of a new clutch from Porsche NZD$3,000 or hae my one rebuilt $1,400. so now waiting on rebuilt clutch and should be away. I have owned my 944 for 8 months and it has spend 5 months of the road. I have nearly rebuilt the whole car now!!!!
