I have a '97 e150 conversion van. "Sometimes" the van vibrates on acceleration. I assumed it was the tranny , but aamco checked it out and said the tranny is fine but did not know the cause of vibration. The best way I know how to describe it is --I get the same type of sound when going over those "ridges?" as you slow up to a toll booth. I take my foot off the peddle, then accelerate again and it's gone. Three mechanics so far have been no help. I just know this will become a bigger problem with the family in tow 500 miles from home:). Any help would be greatly appreciated.
