Well, I thought my 1-2 grind was gone. Between 1000 and 3500 miles on the clock, I had a couple track days and autocross. No grinding at all.

Then driving on the street, I had two grinds between 3500 and 3900 miles. It happened when I did quick shifts between 1-2 at ~4-5000 RPM, but I've been doing that for the past 2500 miles without any grinds. It's not reproducible, so I'm just letting my dealership know about it for now.

And you don’t think you did anything different on those two shifts? Not late off the gas, or late with the clutch?

Honestly, that shouldn't matter.

Nobody can shift perfect 100% of the time, yet most other cars do not grind.

This really does sound like a legit sporadic issue.

But it does matter. If you’ve made 100 shifts with no grinds, and then suddenly get two grinds, wouldn’t you first question whether it was something that you did differently?

Others cars don’t have epically good, super precise gearboxes like these cars do. That requires precise technique. You can slam ****ty shifts all day on other cars because their gearboxes are sloppier.

This whining is laughable. Either learn to shift precisely or sell the car. Porsche ain’t going to do jack about it. And honestly, if a slammed 1-2 shift is a requirement for you, I think you bought the wrong car. Maybe a Dodge Demon would be more appealing.

This whining is similar to people wanting high performance racing brakes, but then complaining when they squeak when they drive around to Cars and Coffee at 30mph.

Mine is a PDK car, so not an issue for me. However, I still think there is something to this. I DID have this same issue on my 08' M3 and it was a legit issue and back then, BMW's shifters were FAR from precise, yet there it was, still an issue.

What a load of bull**** justification. Super precise good gearboxes? Gtfo

If you need to shift a brand new performance car with kid gloves and a 3 breath delay to avoid a grind, there is a problem, even if sporadic

You don’t need kid gloves and you don’t need a three breath delay. You can do it plenty quickly, you just need to do it very well. This car doesn’t tolerate ****ty technique - at all.

And please spare me ‘we’ve all driven manuals for years’. What we’ve all driven are mostly ****ty manuals designed for the mass market for years. And most people haven’t even done that well. The assumption that most owners are great with a stick is laughable. I let a GT4 owning Rennlister test drive my Spyder a few years back and I was shocked at how bad he was with the manual.

I realize you revel in being the cantankerous contrarian here but on this you are simply being obtuse and silly.

I've driven more than 100 manual cars more than a combined million miles. The only cars that have ground are my three Carrera GT's and this one.

To suggest I have to shift this one differently is ludicrous.

I was born in Argentina where automatic cars almost didn't exist when I was young. First automatic I drove was here when I was 32 years old, before that I always had all types of manuals, I compete in 1/4 of a mile in my country with high-power cars and ****ty transmission and never had a single problem. Yesterday I took my 991.2 Manual GT3 for a drive and the shifter is butter, the problem with 1st to 2nd in the spyder is there, I don't know if it will disappear with more miles, but it is not normal. I can assure you that I do not know how to drive an automatic properly because I don't like them at all (My daily is automatic just only for the commute to my work) but I know how to shift a manuals and this is not normal...if you shift fast/hard there is no problem, shifting smooth or being gentle sometimes you find the grind in revs around 4000/5000k (I don't know after that because I'm still in the break-in).

TL;DR as I've mostly tuned out of the discussion. I had grinding as others early on, somewhere around 1500 km IIRC. Never since, even on track. I recall it seemed to be narrowed down to certain production months based on anecdotal evidence. Anybody still tracking issues and production months?

My May 2020 built Spyder has not had any grinds in the last 2000 km. Currently around 6500 km on the odometer. Prior to that, I had 30-40 grinds occur. It wasn't shift speed or technique or clutch timing, it ground when shifting correctly. Just a manufacturing defect. Grinds were frequent before I hit 3500 km roughly (would grind roughly 1 in 15 1->2 shifts). Between 3500-4500 km, grinds became less frequent. Since 4500 km, I haven't had any grinds. I haven't changed my shifting technique at all, I make zero effort to not trigger this grind (other than shifting normally). I've never had any other manual car grind, just this one.

FWIW 500+ miles so far without a grind. Car built June ‘21.

Mine is around the end of March 21 build, but I have only 450 miles..hopefully, it will disappear after the break-in

Forget the 30+ years of experience I have driving manuals. Let's look at the last four and a half years, and focus on only two of my manual cars owned in that time. Those cars are a 2015 Boxster GTS and 2016 GT4. In that time I put 80,000 miles on those cars. In that 80,000 miles I did not have a single grind from either car. Not on the road, not at autocross, and not on track. I had two grinds the first day of owning my 2020 GT4.

Respectfully, no one in their right might could believe I spent 4+ years and 80,000 miles driving those two cars without a single grind and literally step out of the Boxster and into the 718 GT4 and the grinds be a fault in my technique. Because that is what happened, as I owned the cars concurrently.

Luckily I have not experienced any grinds since around 2,500 miles. That is 3+ months and 3,000 miles without a grind. Fingers crossed.

GT4 March 2020 build no grinds since the 2 reported in post#2 at around 1-2000kms. 22648 kms on the dial shifts like butter.
