I have that ticking/knocking sound (in gear moving, idle in park, quiet/goes away in neutral, doesn't increase with revs) which seems to be covered more in the Taurus forums but appears it might be the EPC solenoid. I've also noticed some delay in the 4-3 kick down, along with holding 4th to almost 1100 rpm at slower speeds and needing to either manually pull lever to 3rd or blip the throttle to get it to auto-kick down. It would seem the EPC might be the reason for the ticking, and the 3-4 shift solenoid might be having an issue too. Fluid was flushed after getting the car and still smells fresh and old fluid was NOT burnt/stinky. Thinking the entire valve body could be replaced with an upgraded reman OR just replacing the EPC, 1-2, 2-3, and 3-4 solenoids. Can those be done with trans in the car? i.e. can the valve body be pulled with the trans in place?
