Hey guys, I own a 07 g35 coupe and the engine just got replaced under warranty since it was consuming oil. I told myself to change the clutch while everything will be opened up. I went ahead and purchased the Competition clutch Ultra Lightweight Flywheel and the JWT clutch. I got a call today from the dealer saying that the transmission is making a very loud noise and they're pretty sure it's not flywheel chatter. What do you guys think it could be? I forgot to ask them if they drove the car to make sure it's not flywheel chatter though.

Edit: I had a brand new transmission installed 15000 miles a go
