This is the 2nd Mustang 5spd transmission I have purchased through the dealership and Ford that has the same problem. Concerns of vibration felt through the seats, floor, and steering wheel while traveling at highway speeds! being the 2nd vehicle, I have been battleing the dealership for a whole year and have just now been given the opportnity to meet with a Ford rep.the poblem has been overseen by a Ford tech. Twice with a replacement of driveshaft twice which still hasn't resolved the problem.I have testimony from othr service reps with other dealerships that state they feel there is a problem with the car and it is not the tires!(vibration that is) also mangr. And techs.at a Goodyear tire shop.the dealership"S shop foreman felt the abnormal vibration on a testdrive with me and felt it was out of the ordinary, however, his service mangr. Later went on test drive and stated that he felt there was no problem. Also the Ford rep. Testdrove the car and stated he felt no problem either!. the car has been repaired in the past year over 9 times for the vibration! so there was a precedent already set before the Ford rep. Got involved. My concern is that I still have a vehicle that has anabnormal vibration while traveling between 65-75mph on highway, it has been documented by me, the dealership, and Ford. The vibration keeps coming back and I havebeen told by reputable sources that it could be a safety issue due to the amount of abnormal wear that can happen to my tires from this abnormal vibration I told this to Ford, many months ago, so they switched my tires, including the brand(from Goodyear to michellins)when the Ford rep. Was asked the question by me how is it that th dealer's shop foreman felt the abnormal vibration and he didn't, his response was that it all ended with him no matter who found what!!!this probably seems very convoluded but I am just expressing my concerns with regards to my safety, as well as the safety of my fellow consumers.
