Gear 1-2 grind

My boxster 25 continues to grind 1 to 2 with under 400 miles. The factory service bulletin mentions the spyder and gt4 designed without the mass weight for sportier shifting. The Bxtstr 25 shares the short shifter from the spyder and the gt4. Champion Porsche in Fl. says this grind is normal. If you listen to the you tube video of of the sound posted above this is anything but normal

For those of you that have experienced the 1-2 gear grind I advise you to document and elevate your concerns to Porsche corporate. The company has a long history of denying any responsibility for their design faults. The IMS issue is a good example. My 718 has experienced this problem on my first drive it now has less than 400 miles. It occurs whether hot or cold, low or high revs, slow or fast shifted. To assume it is a brake-in issue is foolish. The you tube video of this problem shows that this is not unique. Champion Porsche here in Florida says they cannot duplicate the issue when they test drove it. They suggested I contact Porsche who told me that unless they can duplicate that issue in the presence of a tech there is nothing they can do. Why not? I have sent that video to friends, racers and race mechanics. Whether it is syncros , shift cables, manufacturing burrs on the gear set, or something else. All who have seen and listened to that sound knows that this is not normal. This Boxster 25 was bought as a gift to myself and I sold my 993 to buy it. The last thing I needed was to be involved in trying to deal with an unresponsive company trying to resolve an issue to an item (MT) invented over a 100 years ago, Whether the resolution to this will be that the issue was fixed or resulted in my pursuit of a lemon law return or possibly even a class action suit when enough of us require new transmissions I am underwhelmed by Porsches response but not surprised.

Just had another grind at 11k miles. It has become less frequent. But it is not gone. I have a clunky shift symptom too that Porsche have also been unable to replicate even though it happens most of the time. Taken it in 3 times now over the life of the car. Trying again at a different dealership next week.

This grinding issue is what sealed going with PDK for me. I'd just hate driving the car and always think this may/may not happen when I shift. Instead I am living with the thought what if the PDK fails (most likely leaks) after the warranty is gone... but at least that is little further out

There is always that proverbial deal breaker and the grinding issue was it for me. I dealt with a transmission on another car that had "temperamental" syncro (and more like damaged/worn) and hated the random grind it exhibited. At least it was repairable.
Otherwise I could have ended up with a manual...

There other reasons (gearing, clutch travel, borderline weak clutch stock, linkage issues) - plus PDK is fun in its own way. But long term reliability of PDK is a concern.

This gear shift has 2 steps.
1) from the previous gear to the middle point.
2) from the middle point to the next gear.
When shifting try 1) without pressing the clutch.
Then just before 2) press the clutch and change to the next gear.

Maybe. But I've been driving manual transmission cars for almost 50 years, and I've never had gears grind, including my 987 spyder and 2 other 987s, and I'm not going to change my technique for this car. It ain't the driver's fault. I've only had it happen 4-5 times in 3k miles, but I'm disappointed at best.

Had a new version of the grind tonight… autoblip was on, traveling casually at about 65 on the highway in 6th. Traffic in front of me slowed down and I went to downshift from 6th to 4th. With the clutch fully pressed, got a big grind as I pulled into 4th. I can’t tell for certain but 6th feels more “notchy” now. The dealer has done absolutely nothing about this because they can’t reproduce it due to the infrequent nature of the problem. I stopped all hard pulls from 1st->2nd and still on casual shifts will find a grind. This might be my final straw with the car but can’t decide what I would buy instead since there is not much available.
