I have a 2010 Stang with V6 and I'm expericing a vibration under excelleration between 50-55 MPH. If I take the overdrive off it goes away. If I power though the 50-55 I dont feel it. Has anyone else expericenced this? Any advice

 

hopefully there is power train warranty left on it,vibration in cabin or steering wheel can you be more specific?

 

If the car is at a stready 50 mph and I accerlerate lightly, I feel a light-medium drivetrain vibration though the gas pedal. Once I'm over 60 mph it goes away. If I lightly fluctuate the gas pedal between 50-55 it vibrates. If I power though 50-55 or take the overdrive off, the car is fine. Thanks for the help. 2010 V6 auto.
