Car Forum / Porsche / Porshe 911 / January 2004Advise Pleeaaassseee - 911SC Gear change
Hi, a sudden problem has appeared and my 911 SC may be out of commision over the holidays :(( The gear shift all of a sudden would not come out of 2nd, eventually I got it to nuetral but couldn't get in to 1st. After many attempts (and more force than what should be required) I got into 2nd and drove the 90 odd kilometers home. Managed to get neutral and its not going into any gear. Can't even move gear lever left or right to 1-2 or 5-R neutral positions. (This is when I'm stopped or moving) Losened linkage behind seats and trien to manually move the gearbox shaft to no avail. Please help with any ideas/advise and more importantly costs!! PS. I'm in South Africa but can convert from DLR or PND to get some idea. Thanks in Advance Angelo 1982 911SC Targa I would say it's hard to tell what the problem is without going inside the tranny, and I have a feeling that's what you are going to have to do, unless it turns out to be a minor linkage problem. I'm not a Porsche mechanic by any definition, but I would be very careful about driving it. If there are any broken parts in the transmission you may do even more harm costing you even more money. When my second gear went out they told me it was hanging by a thread just waiting to drop into other parts of the tranny. Said I was lucky to have stopped when I did. I hate to sound negative about this, but the cost of a tow will probably be far less than any further damage you may do to the car driving it.

So don't move the car, and try to get the gearbox of another SC to have it replaced. If you try at a Porsche garage, it might amount over $6000 good luck Pak, France I appreciate your responses and must add that I consider myself lucky especially after Pak's comments. Next time!!! I stop there and then and wait for a tow-truck. I'm lucky in that only the following need to be replaced:- 1st gear synchro ring 1st gear shifting sleeve 1st gear dog teeth The above cost R4000 (south african rand) +/- $660 I don't know if this is common knowledge or only locally, but the Porsche agency does not supply the dog teeth separately. The 1st gear complete with the dog teeth costs $2000 A local Porsche dealer supplied me with the dog teeth for $250 and at a cost of $50 removed the damaged teath and fitted the new. The box is currently being assembled and I hope to be on the road again by tomorrow (Wednesday).

Due to the festive season the motor was only replaced last night. The good news is that gears 1 to 4 and reverse change easily, even 2nd which was a little tight before is vastly improved. (remember only 1st was found to be damaged). The bad news:- She refuses to shift into 5th, even when stopped. The gear lever moves to the 5th/reverse neutral position but will not move far accross to engage 5th. Any ideas? hopefully adjustments!! or must I have the tranny removed and opened up again and what spares$$$ Regards > I appreciate your responses and must add that I consider myself lucky > especially after Pak's comments.

You can adjust it through a small access hatch in the center of the floor between the back seats. There's an adjustment procedure on http://www.pelicanparts.com Ed Thanks for the tip, unfortunately my mechanic did adjust the linkage and I also attempted according the the "Pelican" directions without any improvement. I still cannot get 5th. Gear lever moves accross to the right into neutral between 5th and Reverse but will not move forward into 5th. Although I can pull it back into Reverse quite easily and with out any "graiting", it feels as if "Reverse" is not 100% engaged even though it drives OK. O yes, a bit of an irritation with 1st as well. No matter how slow I'm moving and if I "double clutch", pause in neutral, etc. I have a slight graiting noise when I change down into 1st. I have to come to a complete stop to avoid this. I didn't have to do this previously. Remember "dog teeth", slip, synchro, for 1st have just been replaced with new. The tranny is coming out again tomorrow and according to the mechanic a complete strip is not necessary as 5th is easily accessable. Correct?

Linkage has been adjusted according to the manual. 1st gear slider, dog teeth and syncro. ring have been replaced. More serious, after removing the tranny a second time to check why 5th wasn't engaging, the mechanic said that the slider teeth were "slightly" damaged and he filed the rough edges away! 5th does engage now but you get the feeling that its not engaged fully. Mechanic says that this could improve with time. Do you agree? Also, is he correct in saying I won't damage anything further by driving the car in this state until cashflow improves for a new 5th gear slider.

No. IMHO what you really need to do is find another mechanic. If you've just had the synchro and slider and dog teeth for first gear replaced, it should NOT act as you describe if you're shifting properly, and it's hard to imagine how a competent mechanic could let you drive the car away without it even being able to shift into fifth gear. Ed >> Any ideas on the following? >> [quoted text clipped - 16 lines] > and it's hard to imagine how a competent mechanic could let you drive > the car away without it even being able to shift into fifth gear. I agree wholeheartedly. Does this person work on Porsches for a living? Or just yours, Angelo? DS 95 993 Coupe Get another mechanic. john 83SC > Any ideas on the following? > [quoted text clipped - 50 lines] > > > > > > Ed Sir, you have a clutch situation, IMHO. Full "throw-out" is not occurring and you will continue to grind away any gearing that gets in the way. Adjusting the linkage is insufficient. Don't waste more money replacing or ablating cogs. As advised, find a good mechanic, Tom Angelo. I live in South Africa too and have an ,83 911 SC coupe. I had similiar problems to yours but not as extensive. A clutch replacement solved the problem. Check if you have sufficient play on the pedal, no play after adjustment - new clutch. If you live in Gauteng, there is an excellent mechanic on the southern side of Johannesburg CBD. I can highly recommend him. Peterp |
