I've had problems with hang down shifts as you describe, that were solved by adding a half can of SeaFoam Trans Tune to the tranny fluid (don't overfill) & driving until the hang shift ceased, then dropped the tranny pan, changed the filter & did a full tranny fluid pump out with new Motorcraft fluid, as outlined in the "how to change your tranny fluid at home" thread.
I have always change my tranny fluid with the specified Motorcraft product, at or before Fords severe service call out, but still have had the tranny act up on my 94 Taurus & 99 Ranger.
Doing the SeaFoam Trans Tune cleaner upper & tranny flush routine, has always cleared them up in a few weeks of driving.
The tranny fluid has always looked ok, normal light pan deposits & clean looking filtran filter & tranny innards, no sludge, gum or varnish deposts visable anywhere, but I still have had problems, so our trannies must be extra sensitive to the slightest gum, varnish, or sludge deposits!!!!
So if you don't have a mechanical or electrical shift solenoid problem & haven't had a tranny fluid pump out & filter change lately, maybe internal tranny deposits should be on your suspect list.
Some thoughts for pondering. Let us know what you find.
