Recently, I have detected a vibration in the dash aroundthe speedometer/gauges area. I only hear it while goingthrough the lower gears, usually first to about third. I've had the car (2006 Mustang GT, manual) since April 06 and have only 2,900 miles on it. I rarely drive it and keep it garaged. I first noticed the vibration about two months ago at about the 2,700 mile point. Anyone else experienced this or know what might be causing the vibration? Thanks in advance for your input.
