Bad Vibrations 1000-2000 rpm help!
The whole car shakes between 1000-2000 rpm! Not at idle or above that exept at WOT in D, look below......
Doenst matter if in D, OD, P or neutral......
It feels like it worse in D than in OD when I drive. When I am at WOT in D it shakes all the time......
I recently replaced my tranny mount so I'll crawl under and check it...otherwise I dont have a clue?????

i'd suspect a miss or dropping a cylinder and not a drive train or suspension problem, they usually only get worse with speed or rpm increase. check the tune up and make sure there isnt a problem there, might want to do a compression test also.
