I had AAMCO install a brand new clutch kit and brand new flywheel on my 2004 Mustang V6 3.9L . When I start my car in neutral I hear what sounds like a chattering noise. It goes away once I release the key. I did not have the problem before dropping it off. AAMCO said it's normal and part of the break in process. I just want to make sure what I was told is right. So, my question is:
Is it normal to hear that type of noise when starting my car?
