My g35 vibrates like crazy when I let off the gas in a higher rev range and it can happen in any gear and I can't tell if I need a new clutch or new rear axle or maybe a whole new transmission if anyone knows what might be wrong please let me know also since that has been happening my car is kinda jumpy in first gear now and I changed my tranny fluid clutch fluid and rear diff fluid and I still have the same issues

 

can you just check it out at a dealers

 

I did when it first started and infiniti claimed they couldn't replicate the problem :/

 

maybe go to the one in Mission Vejo.

 

That's too far but I took my car to a nissan dealer today and the couldn't replicate the problem either...this sucks cause my car clearly has a problem and I just don't know what to do anymore

 

Have the mechanic take a ride with you if you can easily replicate the issue. So it can be pointed out.
