On sunday I got my new 2017 gt pp with 2 miles and today while I was driving home in 6th gear I noticed some weird metal noises coming from the gear box. It is very hard to explain but it only happens on that gear. The car has now 100 miles and just wanted to know if this is normal or it would go away within time.

 

Let your dealer listen to it since it's BRAND NEW!!

 

I got my 2017 GT manual 3 weeks ago, I don't hear any sounds like that! The only sound I hear is changing gears 1-2-3-4 making thump sound when I put it in gear do you hear that also?

 

Hey. New owner here. Got my 2017 gt with performance package and manual transmission on 7/15/17. Love it! But...as someone else mentioned, my wife and I noticed an odd metallic sort of rattle sound. It only happens in 6th gear when the drive train isn't under much load. Like when driving on the interstate and going down hill. I took it to the dealer and they didn't hear the noise. Admittedly, it's not very loud. But, it is there. Maybe it's normal? Maybe it'll go away on its own? Currently have a little over 1k miles. Has anyone got more information on this issue?

 

I just bought a new Mustang GT 6 speed and noticed the same noise. Did you get a resolution re the noise you were hearing?

 

Should NOT hear any metallic sounds from transmission, take it to dealer ASAP

 

Thanks. I had the dealer drive the car but they didn't notice any unusual noises. I'm not sure it's coming from the transmission. It's just an odd metallic sort of thumping sound that I only hear in 6th gear when the drive isn't under any significant load. It might just be something lose. Maybe a heat shield or something. It's just an odd sound.

 

If you know how or when it does it, you drive the car with the tech and show him.

 

That's a good idea. Thank you!
