Picked up a vibration this week.I beleive it is coming from the trans but not possitive.With OD on or off when approaching the 55-65 mph the car gets a vibration that is not continuos as in it never stops but is in the sense that it is a intermittent vibration.Shakes pretty good through the sterring wheel lasts about 1 sec than goes away for 2 then comes back again for a second and so on.When accelerating past 65 it seems a die down a bit but does not go away.When holding a steady speed between 55-65 and at the same time slightly tapping on the brake the trans seems to down shift a bit but vibration doesnt go away.Does everyone beleive as i do that i have some type of trans problem? Any suggestions? thanks
