The AOD in my bronco is buzzing and I can feel it through the sfifter,its more noticable at idle and goes away with more RPMs. It works just fine and had no problems with it except for the buzzing,when I got the trans it was supposed to be rebuilt but when I dropped the pan after installing I noticed parts in the pan so I had it rebuilt again. It had wrong parts in it and thinking I should have junked it and got another trans since the builder said it had a bunch of metal that went through the trans,anyone have any ideas on whay its buzzing.
