Even in my 1970 911E dogleg, I would never need to double-clutch when shifting gears. The car does feel more natural going into neutral before shifting into the next gear, but I never need to release the clutch & engage it again for a smoother shift.

In the GT3, I actually find myself flat-shifting a lot now. Otherwise, the synchros feel best with a single-clutch direct shift into the next gear.

You’re not wrong- that is fairly common with F355s but mine does not do it. Goes in smoothly to second on first cold shift of the day! Ironically, my 993 has a worn second gear synchro that does require a double clutch shift to 2nd on the first drive of the day.

Change your title to.....BUT the rest of the car is sooooo gooooood.

IMO it's of the best. I'm no Chris Harris but we share the same beliefs here.

Hey! Just tried to edit thread title as you suggested but seems it's already locked
Btw the ECU seems to have mind of its own as sometimes it will let you do it other times it will bog down as described above....
Will try to decipher system behavior over the next few weeks.

Yes, it is a bit mysterious how the algorithm works...

I've been trying triple clutch up shifts recently, and I find them to be really enjoyable actually. I find it upsetting though that I can't reset the needle on my in-car LP player while moving, I can't believe Porsche doesn't let me do this.

Right about now it would be really helpful if someone from PCNA, AP or one of his reports could chime in as to decision process that went into having this setup in the manual GT3's but not in GT4/Spyder manuals...

One nice feature about the manual GT3 is how quickly revs drop so the sport button seems to rev match not only in downshift but even on upshift if latter is done lazily..

It's called flat up shift function, outlined in the owners manual. It allows you to keep the throttle pressed on upshifts, makes them super fast and smooth. Unfortunate it doesn't exist on the 981/718 platform with gt4/spyder. Also doesn't exist on 911R.. just 991.2 GT3 manual onwards. One of my most favorite features for track and even street use... just keep the throttle down and press the clutch to shift.

Thanks for sharing, I could have used this flat shift nugget on the way back from the F1 race in Quebec when running into a cool guy in his Trackhawk and another 991.2 but a winged car. We had fun for about 30 min.

exactly!! I started double clutch downshifting when I got my manual 575m, car liked it better. Now I do it in all my cars by habit because it’s plain just more fun, a dance when downshifting multiple gears. Kind of like why some people like grinding and tamping their espresso when their nespresso machine works fine.

I’m bummed to hear this since I’ve been looking forward to finding a manual 991/992 gt3.

Ffre92

you should thank the Italian car gods for your good fortune, it is not common!

both my 575 and 430 crunch into 2nd when cold, fine when warm

Ffre92

Fair point. But if that is the logic, then why did you buy a 6mt gt3 in the first place? Im assuming it’s because it’s more engaging and fun to drive a manual, not because of any performance reasons. Auto blip and flat foot shifting are steps towards being a pseudo pdk. If I want to enjoy my drive I’d like as much control of my engine and gearbox as possible. If I wanted to be as fast as possible (which I don’t) I would just get a pdk. I don’t think an “in between” transmission makes sense for me.

Software upgrade can remove the soft rev limit in neutral. Is double clutching nesassary since the car will auto rev match if you hold the throttle while shifting?

GrantG

Double-clutching (revving to match with clutch pedal unpressed) spins the input shaft of the transmission which provides a different (smoother, more effortless) downshift than just spinning the flywheel. This is generally redundant with the synchronization function of a modern gearbox in excellent shape at operating temperature (but helps when one or more of these conditions is not met or when performing a challenging synchronization, like going into 1st gear from 25mph).

To try to answer your question, I would say that I buy a certain transmission, a manual, but I'm happy for it to be as refined as possible.

Just for kicks, here is a video of a Porsche I drove, a 962-derived Koenig c62, with possibly the hardest ever to use manual transmission.. it was totally recalcitrant, shifting into first required first shifting into second, impossible to find gears, super long 200mph ratios with a power clutch function button necessary because the clutch was so stiff as it was made to handle 1000 turbocharged horsepower in lemans trim...


I edited out the parts where I really struggled, but you can tell already at the beginning how tough this was.

So, Do I prefer this beast of a 6-speed it because it's more raw and unrefined? Hell no!!! It's a crazy experience and fun to say I did it, but I want no part of it. Modern is better, and I appreciate even more my buttery smooth 6-speed in my gt3 with all kinds of great synchros, rev match function, and flat up shift.

Does that mean I want a Pdk? No... I just want the best possible manual transmission because I've tried the very worst Porsche manual, both on road and on track, and I want the best perfoming one. That DOESNT mean it is less engaging though.

Hopefully my logic doesn't have too many holes in it, but I love where the convo is going and would like to understand what I'm missing.
