987 manual gearbox vs 997 gearbox
Discussion
These are different gearboxes are they not? Can anyone tell me how they compare?
I find the 987 gearbox a charm although I know some people will say they've had better.
I'm still waiting for a suitable 997 gen 2 manual to come on the market but I've read a lot about gearbox failures which isn't great but what I think is worse is quite a few people have complained about difficulty shifting between certain gears or when that the box is stubborn when cold.
There are are a ton of PDK cars for sale which I want to avoid, but at the same time I don't want a 911 with a crappy manual gearbox.

I have a 997.2 C4S and have read about the manual boxes being notchy and stubborn when cold. Especially shifting into first and from second to third. Mine fortunately is perfect and I have never had any issues with it, but then again I'm not exactly hard on it. It does say in my manual though to pull away in second gear when possible.
I had a tremec 6 speed manual in an LS engined V8 before that didn't like 1st gear when cold but shifting into 2nd then back to 1st was much smoother.

Does the handbook really say pull away in 2nd? I am surprised.
I do enjoy manuals but not sure I like the hassle of living with a quirky gearbox or going through the hassle of having it replaced (even under OPC warranty).
Would hate to buy a PDK car though and get bored.
I'm sure it does but I'm having doubts now that you've asked. I do enjoy manuals but not sure I like the hassle of living with a quirky gearbox or going through the hassle of having it replaced (even under OPC warranty).

I genuinely don't think you'd get bored of a PDK car any quicker than a manual if the truth be told. Launch control seems a hoot, you can't really over rev them and they're faster.

If the manual says that, it's about as wrong as can be! These engines hate to be laboured and will respond by scoring bores. Keep the revs up!I had a tremec 6 speed manual in an LS engined V8 before that didn't like 1st gear when cold but shifting into 2nd then back to 1st was much smoother.

I have a 997.2 C2S, manual with the factory SSK fitted. Yes, when it's cold it requires deliberate and careful shifting - nothing major, just a fairly relaxed attitude and some half-decent mechanical empathy. I'm lucky - my exit is a km of potholed drive and 4km of single track road, so by the time I've reached the main road, it is starting to loosen up. Remembering that these cars take 15-20km to get warm enough to really start using the performance then that doesn't bother me in the slightest. And the upside is that the manual/SSK combination is sublime once everything is up to temperature - streets ahead of the original 7-speeder in the 991 - that was like stirring porridge in comparison. I haven't driven a manual 987 so can't comment there, but isn't it a minor variant on the 997 box?
I put a new box in my 997 C4S - think I damaged the synchros changing too fast, with my short shifter.
I would not install another short shifter after it gave me a £4000 bill last year - now change in more of a relaxed way
The box is certainly stiff when cold but really, that goes adfter 3-4 miles of driving
I have not heard of a lot of failures they are supposed to be robust
I believe the box is different in the 987 and 997 but from same manufacturer

I don't think failing to rev match would bust a synchro, would it? More wear perhaps, but not likely to be at fault for a sudden failure. The synchro on 1st and 2nd is knackered in my 997.2 S, which is apparently a fairly common fault that arises at middling mileages. I think it's one of those faults that is a mixture of (mostly) a slight design flaw that manifests in some cars more than others and a bit of driver misuse. There are far too many very similar stories for there not to be a weakness in the design (even if it only causes an issue for a certain proportion of boxes).

Sounds crazy.
I even "feel" for the clutch when reversing in my 996, as reverse gear seems a bit tall. What does the rest of the blurb state? The bit that's out of the pic, re first gear?
It says "Moving off in 1st gear can increase fuel consumption" in my 987.2 manual.I even "feel" for the clutch when reversing in my 996, as reverse gear seems a bit tall. What does the rest of the blurb state? The bit that's out of the pic, re first gear?

I should file this under "Things to point out when people say Porsche knows best".
That is utterly stupid advice. You will have to ride the clutch to pull off in 2nd (as 2nd is quite long). And these engines (well, at least true for pre-DFI) hate low rev work.
I cannot see any good reason to use 2nd to pull off, to be honest.
In fact, I typically shift down to 1st if the road speed drops below about 10mph. 2nd really is too long to be used as a crawling gear without labouring the engine or slipping the clutch.

Anyway I must have jinxed something because my gearbox cable has just snapped and left the car un-driveable

Currently got an automatic courtesy car and its reminded me why I hate automatics!
