After I wrote the below, I found: 1: Search "Ford Parts", I found 1 site that looked inviting but there=20 are more: http://www.fordparts.com/default.aspx?gnav=3Dfoot:features 2: Enter Vin number, and click appropriate links, should take you to a=20 parts diagram. There appeared to be a half dozen differentmodels for=20 that vehicle. Don't know which model transmission that is, but might be a C-4 or C-6.=20 Is it and overdrive transmission? It might be an E4OD. There should be=20 ametal or white plastic film tag on the transmission that will have a=20 part number on it that will define the model/variation specifically.=20 Search (Google) that number, should be able to find a parts list that=20 will define the part, number and price. When you say donut, I'll go a little further, like the top of an aerosol=20 can, but not quite as high? Could be a modulator or a piston servo. How=20 is the piece held in place? spring clip, bracket and screws? A picture=20 is worth 1000 words. Where is it leaking, did it rust through a hole? At a joint where it=20 comes apart? Clean area thoroughly, then start very briefly. Might just=20 be needing a replacement O-ring. Be careful dissembling there could be=20 strong springs, and/or fluids under high pressure. Might be safer to=20 take to a shop. If the transmission doesn't have to be removed should be=20 inexpensive. Might be you can get it apart and not back together, then=20 expensive tow. :( On 5/7/13 2:56 PM, YES NOPE9 wrote: > This is my 3rd day of scanning the web for an answer to a question. > > There is a leak on a 1996 Ford Explorer AWD V6 Automatic transmission. > There are two donut sized protrusions on the passenger side of the the tr= ansmission. > The one most forward is jetting fluid. > What are these protrusions for ? > > Gus --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
