AOD trq converter ?

I don't think so. The torque converter lockup is electronically controlled on the AODE, whereas the AOD is mechanical.
Besides, the stock converters on AODE trannies are crapola because they're the ones that had all of the 3-4 shudder problems (something which caused Ford to switch all the newer cars to Mercon V, which helps prevent it). Using a TC from a late-model 4R70W tranny would be preferrable (99+ GT models), but still, there's still the difference in electronic versus mechanical lockup.

No it will not work. I take it you got the shifter arm changed out. AODE is a lock up converter and an AOD HAS NO LOCK UP. I have argued with people up here about an AOD that it has no lock up. If you look at a hydraulic chart for an AOD it has no lock up. A lock up converter has a clutch in it and a non lock up converter doesnt have one.
Yeah you will need a lockup converter 
Non lockup converters for an AOD means no 4th gear. All he meant is the AODE has a lockup that engages in the torque converter itself and the AOD has a lockup that is engaged in the transmission via a shaft that is permanently locked into the converter housing.

Sorry to say this fox but you are wrong. 4th gear in an AOD is the OD band and the intermediate clutches come on. Nothing to do with the converter. I am going to post info on the AOD. What comes on for what gear and hydraulic charts so I can prove to everyone that an AOD has no lock up. 3rd gear is 1:1 and 4th gear is .75:1 that is the gear ratio.
You're just splitting hairs now... the intermediate shaft in the AOD is ALWAYS locked into the back of the torque converter housing otherwise your converter would be slipping all the time. And as I said before AOD engages the lockup internally when it engages the direct clutches since that shaft is ALWAYS locked up in the converter housing. The AOD converters are marketed as lockup (intermediate shaft splines in rear of case housing) or non-lockup (made for a 1 piece input shaft no splines so no overdrive and constant converter slippage) not my fault they weren't good enough on their terminology.
**OD ratio is .67:1 or .68:1 IIRC
