I'm having troubles with ford AOD transmissions. I work at a junkyard. I will pull an AOD that is working fine and put in the warehouse. Sell it, and it comes straight back as not working. I have had this happen many times and know the mechanics who put them in. Some junkyard have even quit selling ford AOD trannys for the same reason. If you have any Ideas why this is please let me know. I have talked to many people who haved work on trannys for more than 15 years and the don't know why either.

These transmissions need proper adjustment of the throttle valve(a cable attach to the throttle and move a pressure valve in the valve body)to control working pressure,many amateurs or so-called shade tree mechanics are not familiar with this.It is my best guess,hope this helps.

Hard to answer. If, you live in a Hill/Mountain area this may be the problem. People need to not use the OD it hard on the transmission. The OD is for when we on the freeway and moving on down the road. I not remember off hand, but, I thinking the OD use a .7:1 ratio so it put a stress on it shifting down all the time in hills. My Chevy Truck, I pull a 32' 5th wheel camper, it have that 700-R4 OD. When I bought the truck my friend that rebuilds transmissions told me; "I get a lot of those". I asked, what can I do? He said; "When you pulling the 5th wheel, do not use the OD"! I have done that and it a 1990 been pulling that 5th wheel for 12 years and it still going. I changed the Fluid and Filter once when I bought it in 1994.
But, if you not live where there a lot of hills or mountains, then I just wasted my story and not know. :-p

To add to Carmen Nguyen's excellent answer, those specific transmissions were famous for burning out the direct clutches and overdrive bands in their time. The hollow input shafts, exclusive to that particular transmission, were also another weak link. For this reason, when Ford introduced the AOD-E/4R70W transmission (the AOD's replacement), they changed the internal setup to use a "stub shaft" between the input and output shafts, while using a conventional lock-up type torque converter, which replaced the hollow and solid input shaft setup on the AOD, which had the solid shaft "locked" to the engine crankshaft, meaning this shaft would be spinning when the engine is running, regardless of manual lever selection.

It relies upon on the motor vehicle it got here from. frequently, the latest kind 365 days autos (ie. '87 to 'ninety 3 Mustangs, 'ninety to 'ninety one C.V., G.M. & T.C.) are the main suitable ones. remember, if it comes from a 'police interceptor' C.V., there is not any instruction manual first equipment decision on those specific fashions. i've got faith those transmissions have been customary for burning out the overdrive bands and direct clutches. the different susceptible spot on those transmissions, is the hollow enter shaft. in case you will build one as much as face up to 330 HP, you would be extra powerful stated to attempt to pirate aspects from an AOD-E or 4R70W setup. i've got faith there are extremely some inner aspects which will interchange between the two, in case you do your homework. wish this helps. solid success.

I'm with Carman. My guess would be that you need to offer free TV cable installation/adjustment service with your transmissions.
If the TV cable gets unhooked they won't shift, if I remember right.
