Wow...kind of hard to believe that changing the transmission oil would fix the vibration problem. I'm taking mine into the dealer on Tuesday and I'll mention Luca's solution.

I wonder if there is a service bulletin on this one???

I know, It's hard to believe but that's it!!!!
Remember to clean the transmition before putting the new oil.

Do they need to open it up? Or do they just flush it out? Thanks.

You have to open it and to clean every single part to remove the dirt and then put a new oil.

Wow, that sounds like a lot of work! <img border="0" title="" alt="[Eek!]" src="eek.gif" /> Did they do it under warranty?

Ok....I finally was able to get my car to the dealer. At first they said that the vibration was normal, but then decided to bleed the clutch slave cylinder. They said there "was some air in the system".

The vibration is much reduced, in fact not present in shifts above 4000 rpm if I do a more leisurely shift. If I shift really fast to keep the rpms up I still feel a little high frequency vibration in the clutch pedal (kinda like how ABS feels on the brake pedal). The dealer said this is normal for Turbos....

Its much better than it was, but still there. I wonder if there might still be a little air in the system?

Anyone else had any experience with this????
