I am guessing that you guys are feeling more vibration or shudder then I am. If that is the case I would make some more noise at the dealer untilled Ford comes up with a solution. Maybe they just have not gotten some good examples of the problem?

 

MY car is in the shope for the last two weeks they are trying to locate the problem, so far no luck. I will post as soon as I know so everyone with the vibaration problem will know how to fix it.

 

I'm telling you its not going to be resolve! You have to have a automatic dropped in to fix ford ain't budging on this its normal to them

 

I have a 2013 Mustang V6 manual with 3.31 axle. Worked fine until 65K miles, then began showing vibration when decelerating in gear from 3000 - 1750 rpm. Shakes the whole car. I demonstrated it to the Ford dealer, who agreed that it was an issue. Sat at dealership 5 days and Ford said it was within design parameters. Oh really? There is NO WAY any person would buy this car. I even went so far as to replace the stock driveshaft with an aluminum 1 piece unit and it did nothing to resolve the problem. In fact when you rev the engine in neutral you can feel the unnatural vibration. I am at wits end as to what the next step is. Any ideas appreciated.

 

Did you check the motor mounts? What about the transmission mounts?

 

That is the next thing I am going to look at. Thanks.
