Hey folks, I have a 2018 Mustang GT with 22k miles. I am noticing a fairly loud “rattling” noise….would be the best way I can describe it. It only happens around 1500-2100 rpms and with barley any pressure on the throttle almost like sustaining the same speed. It happens in all 6 gears (manual) but seems to be most prevalent in 1-3. That is probably because of less road noise though. If I accelerate pass 1500-2100 rpms without letting out of the throttle or sustaining a certain speed in that range I don’t really hear the sound.

Anybody have any ideas? The techs at the dealership are clueless and said it was my exhaust and bent it or something only to create a new different noise and the other noise has not changed.

Hi,

I have a similar issue with my 10R80, the shops can't seem to find anything wrong with the car. Super annoying, happens when a little bit of throttle is applied and the RPMs go slightly up, then come down (like 100-200rpm) and the shakes come. Did you ever find a solution to this?
