Welcome Tommy. The Mark VII AOD is slightly different than other AOD's, the output shaft and tail housing basically the big differences. Most AOD's can be used to build a replacement for yours(using your output shaft and housing as example). But to directly replace that one is tough, those Mark VII AOD's are kind of scarce.

You need to know what the AOD you find comes out of, what model, and year. Ideally you want an 89-93 model AOD, the early 80's(81-85ish) have a few inferior parts inside. Any guts of any AOD will swap into any other AOD. So the guts are what you would like to improve with, so a 93 Mustang AOD as example could be used to build with your AOD, into a solid trans.

I suggest searching within your area that you can reach, for any buildable AOD from a 88-93 Mark VII or Mustang. Don't buy one that is already burned up(dark almost black fluid inside). A burned up trans is very likely to fail again in a much shorter time than wanted. You can settle for a Mustang AOD, using that and yours, to have the better one rebuilt.

Thanks everyone, I did not know that I should state my location. I am located in Prince George County, Maryland. The possibly donor transmission is located in the state of Washington. Thanks everyone for your help. In the possible donor trannys will I need to change out the tail housing and other parts? Thanks.

I am sure there is an AOD for the Mark closer than Washington. Price is always a consideration along with shipping cost. 8-)

Yes, find one close to you, or for shipping one, it would have to be ready to go bolt in perfect. I'd tell you to rebuild the one you have, but the pre 86ish AOD's were weaker when new, versus the improved units later on. Ford kept discovering weak links, and upgraded over the years. The next generation of four speed automatics were the 4R70W, made through the end of Crown Vics. Any guts from any of those can be used in various ways, inside any AOD, so Ford maintained the overall structure from 1981 to 2011 or so. The first several years are just risky to rebuild, tiny OD servos("C" version), two clutch 2nd gears, poor fluid lubrication in the output shafts, weak OD(direct) clutch drum, weak one way clutch, etc. It's just easier to begin with a 1988 or newer AOD, which there were countless units made.

Look where you are, for a good AOD from a Mustang in the 1988-1993 models, or similar 88-92 Mark VII. Other AOD's in that year range can also work from trucks or other cars, but more of the Mark VII transmission is needed(swapped into it).

It isn't required but it helps anyone reading your posts. We some times have car issues related to our locations like freezing or over heating. We also enter our vehicle information so we don't have to continually tell people which car we're talking about.
