Chattering when cold
First time posting here and i need some help figuring out a problem with my 350z. I recently replaced my clutch and flywheel to a JWT 14 lb lightweight flywheel and clutch. The techs who did the job messed up and put some GL5 oil in my transmission and i didn't notice until about 5 days later when my transmission would grind when going into 5th. I brought the car back and they put some Factory Nissan GL4 and the grinding went away. But now, there's a chatter around 3 - 4000 rpm when driving the car cold. It lasts for 5 - 10 mins and slowly fades away when warming up. The sound is almost like the flywheel chatter but at higher rpms, or maybe even a bad throwout bearing like noise. Any idea what this could be and what could fix it? Thanks.

I noticed a marked increase in clutch chatter when I switched over to the JWT 14 lb flywheel. It's about half the weight of the stock dual mass flywheel. The "cement mixer" sound is one of the things you'll have to live with. If you want less chatter, you should go to a heavier flywheel.
