Slipping Gear
Twice today my car reached up from 3rd to 4th but landed in neutral or so it seemed. Both times I was accelerating moderately hard - thankfully not coming out of a corner. Both times backing off the accelerator engaged a gear.
Anyone experienced anything like this before?

I was not backing off in either case that I experienced this. It was constant, smooth moderately hard acceleration in a straight line. This is confirmed by the the engine speed almost redlining both times it missed the gear.
Ive been driving these cars for years. This is the first time Ive experienced this.

Had a third moment yesterday pulling away from a standstill at a junction. It felt like bad clutch engagement ie some traction but also some slippage.
My service guy said that if there was a gearbox problem I would see a warning light. Keep watching, if it keeps happening, well need to investigate 🙄.
Does this warning light include clutch problems? I know the clutch is supposed to be a life of the car deal but that is what it felt like yesterday.
i should add that Ive have car from new and Ive never used launch control. I drive it hard but only once it is warm. Nor has it been tracked.

I could echo all your usage comments in the 11 month now I have owned my 4S ....and have never experienced anything of the above in your or others submissions. I know this does not help your case as such, but I just ant to add in a "not normal" supposition , as frequently in these things one only hears from those experiencing something perceived as a problem.
My un-warranted opinion ( and I am not a Porsche experienced engineer, but electric and mechanical engineer by life long career and education ) is that it does not suggest normal function. Manufactures like to hint at "features" etc to explain away such small blips and unexplained anomalies which is basically because of 2 things. They don't want to address ( hoping its small numbers) and they don't want to admit a commercial liability ( an area of my specific work experience)
Saying that, if I hear from a numerically significant number of sources that this is "normal" behaviors AND there is no negative outcome long term .....I like anyone reasonable would accept the original premise. I would be skeptical, and now I have something to worry about in my car !!!

Im beginning to wonder if this issue isnt to do with learned driver style software.
does anyone know how to clear down any learning?
In a couple of my other cars there was a process that required turning the ignition and pressing the accelerator pedal for several seconds In order to factory reset the gearbox.
The Problem seems to be confined to Normal mode which I tend to use on warm-up and in town traffic. Today, you would not believe the car used a PDK. It felt like an old automatic gearbox with really slow shifts. However, once I pressed on in SPORT, everything seemed ok.
Any and all thoughts and advice invited.
cheers J

It does sound very promising given that the 992 has a version of the Panamera gearbox I believe.
Will report back once I have tried.

OK, weather was good enough to go for a drive today.
i performed the shorter reset procedure including pressing the accelerator at 90 seconds during each 3 minute cycle.
Im not sure this still works. I didnt have the whole missed gear drama today but in Normal mode the car feels like it has a conventional automatic gear box. Significant lag before kick down, slow gear transitions, and clattering into first on coming to a halt.
this is the same car I criticised for the PDK programming now making gear changes almost imperceptible.
Something is not as good as it once was
