Hi Scotty,

I’ve just discovered your videos and I’m really enjoying them! I have a question about my 2013 V6 convertible Mustang (standard transmission). There is about 80,000 miles on the car and I drive it often. Over the last six months, I have noticed a vibration when decelerating, especially around 2000-2500 rpms in 2nd or 3rd gear. My online research indicates this may be caused by the “dual-mass flywheel”. It appears to be a known issue but many of the online folks say it’s not a problem and is just a normal part of driving this Mustang.

I’m not a motor guy but I do find it interesting and would love to learn more. I wanted to know if it’s something to worry about. The vibration does go away if I push in the clutch / change gears / speed up etc.

PS: I bought the car because I wanted the new Miata convertible but I had to negotiate with my wife because she thought I’d need four seats (she’s right of course). Mostly, I’ve owned Honda’s over the years. (I want Toyotas now that I’ve watched your videos!)

All the best,

Ivan – Pittsburgh PA

I'd live with it and put in a non dual mass flywheel if it ever broke.
