I don't plan on having the dealer do anything other than remove the deffective box and replace it with the new box. In between I'd take the new box to Copans, about 2 hrs. from my house. Have the gears/LSD installed and then back to the dealer. Obviously the warranty on the trans/LSD is gone.

3rd gear failed on my GT4 last night. Shifted into 3rd at 6K rpm, then the revs climbed to near redline, and dropped to idle. During this the dash flashed 1st and 5th gear. There was no pop or grinding, but just a disengagement.
9,500 miles and no track time.
No modifications.

Dealer ordered the 1 remaining transmission sitting in Atlanta.

Just a heads up that our replacement 3rd gears will be for sake Jan 2. Let me know if you need help fixing a mechanic who can install one. Not that many shops have been inside these boxes and you will want to be particular about who does the work. It’s not an easy gearbox to Service and requires making a couple of soecislvtools.

they make a bit of noise. We have only sold them to GTB class Club racers so far. It’s the gear they always wear out. No GT4 street sales to date.maybe if you start a new thread asking some of Sharkwerks, BGB and other shops’ customers can remark about the noise of our gears. I don’t notice them anymore but you should get outside input on it. It won’t matter that the ratio is different. Noise will be the same.

Busted my today at Laguna - car shuttered briefly after shifting into 3rd then nothing. I plan on taking it to Porsche of Stevens Creek tomorrow. I haven't talked to them yet so no idea how long it will take to replace, hopefully not long I got another event planned in a month.
