PDK

[Joao]

Dear all,

I own a 997 Carrera 2 with PDK and sport plus that performe really well. However I have a question about PDK: When I downshift from 4th to 3th gear around 3.000/3.500 RPM in normal mode, with the wheel padles, I can feel a kind of "lurching" in the transmission. I have 3.000 Klms now. Question to experts in PDK: Is that normal ?

Thanks for your help

Probably not. I suggest you ask your dealer to take a look.

Thank you very much.

Already done. Dealer says all is ok and that there are no any updates to my specific car (it's from the end of May 2010). This (a light schok in the transmission - as when you engage a manual gear with the wrong RPM - only arives when downshifting by hand from 4th to 3th and cuting the gas at the same time, in D and S. Didn't try S+ yet. If in automatic the downshifting is perfect.

Any knowlidge about this ?

Thanks a lot,

Joao

In my wifes GTI (with DSG -- VW's name for the dual-clutch automatic transmission) it does something similar sometimes. Remember how it works by basically keeping the other clutch ready for the next gear to switch super fast. If it ends up having to switch the other way it doesn't have the right gear ready and it'll basically be a (relatively) slow gear change. I think that might explain the "lurch" or "shock" as you call it?

I had felt something like you have described in my Cayman S. The car had almost 17000 miles on it when I traded it. It was never an issue beyond an occasional extremely short clunk. I think it may caused by the lifting and shifting at the same time. The computer may get caught out on those brief occasions.

Dear all. Thank you very much. I hope you had a Merry Christmas and I wish you all a Happy New Year. The car has now 13.000 Klms and is doing better, even if the slight clunk when engaging the third gear from forth, by hand, can appear occasionally, depending of the engine RPM. But if I shift very, very fast from 5th, 4th, 3th, I brake strongly at the same time - all is ok. The same if I do it at 4000 RPM or more. In this case the computer finds the right matching RPM. It is a minor issue, but I think that our friends in Porsche should find a solution to this in a such advanced machine that it's the better car in the world, any way. One intresting point: PDK box gives his better when pushed hard. All the best to you all. Joao
