Hey guys. I have an 04 6MT G Coupe and I have been having some strange rattling sounds that I have never heard before. It occurs when I am accelerating quite aggressively and gets prettly loud over 3000 rpm. There is also major vibrations on the shifter when over 3000 rpm. I had my transmission replaced under warranty about 10000 mi ago, and also had the JWT clutch and flywheel put in. Just wanted any input before I take it to the dealership. Thanks in advance.
