The real fix is to get rid of it. The AOD is comparable to the Ranger Automatics when they're in stock form.

However, if you want to keep it, I'd suspect the sealing rings, drum seals, and would recommend a good valve body removal and cleaning. Remove each valve individually and clean the varnish and crap out, and whatever else could cause the valves to stick. You may also wanna check the governor and it's valve. In all honesty, the governor and it's valve may be the easier check than the rest, and tends to be a common problem on AOD's.

This is one of those things that either needs to happen regular, or never. Because if you change it the first time with 70xxx or so the new fluid loosens up all the build up left from the old stuff and causes them to go out. IF its done every 50k or so then typically it causes no problems. That being said i drive only Standards because i was sick of dealing with autos.

The opinion about changing the fluid and filter at higher mileage differs depending on who you ask. Most people say changing it causes damage. Other people say that the damage that appears after the change is strictly coincidental and that the transmission was already on it's way out before the filter and fluid change. I personally don't put too much into the "damage caused by the fluid/filter" theory since most people who believe in this perform the fluid/filter change on a transmission with over 100,000 miles. At that mileage, it's quite understandable if the transmission suddenly goes out since it had very little maintenance done on it. With used vehicles, you have absolutely no idea what was done a vehicle, so you pretty much just have to hope it's gonna be alright. My Ranger had 43,000 miles on it when I decided to change the fluid and filter, and luckily for me I found that the filter and the transmission pan gasket were not original, therefore I know it has been changed at least once before I got the truck.
