Manual Transmission Vibration while Driving

Manual Transmission Vibration while Driving
Note: I've done a few searches and only found tramsission issues while at "idle". However, my problem is different.
Setup: '04 23k mile 350z on a smooth road with no stereo and relatively new balanced front tires.
Scenerio: I have feel severe vibrations from the stick shifter and it shakes the car so bad that it's hard to see out the rearview mirror very well.
There is no grinding noise while shifting. However, all the vibration feels like it comming from the transmission through the shifter. I know that some vibration is normal for this car. This vibration is much heaver than an other 350z that Ive driven and I feel it through all the gears at any speed, especially at engine breaking.
This sounds to me like the trany is going bad. Anyone have this issue? How can I get the transmission replaced under warranty before it fails? TSB?

Actually, its pretty unlikely that severe vibration would be a tranny problem.
Its much more likely either an engine problem, or possibly a U joint/driveshaft problem.
Since both ate connected to the tranny, and the tranny is really in the passenger compartment, it feels like its coming from the tranny.

From your description it does sound like driveshaft, but go get it checked asap and don't take no for answer from the dealer!!!!!!!!
If it's the driveshaft you will feel harmonic vibration through your pedals, the seat of your pants, trans and just makes the car an absolute handful to keep on the straight and makes it feel like the alignment is out as well in my personal experience. I've just had my '04's driveshaft replaced under warranty just over month ago and other parts that were wrecked by the vibration because the whole ordeal was dragged out unneccessarily. U joints stuffed both ends of the driveshaft. Vibrates the whole car and if it's not dealt to promptly it will destroy other parts. In my zeds case it wrecked the fuel pump, shocks, cd player, half shafts and a few other parts. It's a 10 minute job for your dealer to drop the drive shaft out to inspect.
I personally will be extremely interested how you get on. Good luck & don't let them flog you off with "we can not replicate this problem"!!!!!

I have the same problem you are describing. The dealer went for a test drive with me and said it could be the flywheel but I think it is the driveshaft. My car vibrates mostly at around 3500rpm when decelerating, and also while in
5th or 6th gear under hard acceleration. I know it is not comming from my engine because that was replaced already! and the vibration is still there and gettting worse every day.

2003, 60k, just so you know I have noticed the vibration for about a year, and have brought it up with the dealer before but now it is really bad and I was finally able to replicate this on my test drive.

So what is your dealer doing about your zed capeland if they've been able to replicate. Did they tell you what they think it is????

Bump.
Marshall, how are you getting on with the vibration in your zed? Did your dealer sort it out??
I had my driveshaft replaced one month ago, done 2k so far and this new driveshaft is stuffed already. I know what causes this. You may want to send me a pm and I'll explain.

All the other 14 x 350's I've driven seem to have a very light harmonic, but no where near the huge harmonics that my zed has. Any car that can basically destroy a brand new driveshaft in such an extremely short period of time, has serious issues and to the point in the rare occassion I have to drive to my mechanic's workshop again, having to drive barefoot to keep my foot on the accelerator.
So in my 350's case once again, when the driveshaft is out, it has a very stiff movement in the U-joint, thusly not moving as it should and creating the harmonic.
If you watch "The 350Z Shock" one of the test drivers even comments on the driveshaft harmonics. In most cases would be nothing to worry about.
Anyone know if the 06 350 has had any driveshaft changes made?
Also one thing that may cause a few problems as it has with my 350, is stones caught in the control arms. Get all wedged in and can upset the suspension.
