Comon issue with the AOD trans. The overdrive band gets worn and burnt, not allowing the trans to shift into overdrive, it gets worst over time then stops going into gear altogether. To replace it involves tearing into the trans. So your looking at a rebuild at a min.

Look to see if the transmission throttle valve grommet right below the engine air intake is still in place. Ford made these out of plastic and they often get brittle with age and break. There was an aftermarket copper replacement part that will last forever. If this part breaks and the cable is left to dangle the fourth gear will quickly burn up.

The kick down cable can also stretch with time, causing the same issue with overdrive burning out. The carbureted version used a kick down rod, and I know of one that is still working like new at almost 1,000,000 miles, and we have had 4 in our family that have exceeded 200,000 miles with not one bit of trouble. The transmissions outlived the cars.
