Its a good idea. 

Get a 4R70W out of a later model v6 mustang, 99+.  That transmission is stronger than your current AOD.  Do the mods I mentioned and enjoy.  In your situation you will gain many things.  MAF (something you should have already done), a better transmission and transmission shift point tune ability.

4r70w all the way:evilgrin:
You would need a core 4r70w gear set for the parts anyway, so why not use that one to begin with. It already has the mods. The question after that would be do you want to go manual shift valve body or electronic shift?

Nope sure isn't..  To run a 4r70w with an AODE controller you have to change the Torque Converter Solenoid and the valve body controller with units out of an AODE.  After those modifications it will work.  If you don't it will burn the EEC up.


?????  The only difference I can think of is '98 and up.  The AODEs, and early 4Rs had the same internal WIRE harness and bulkhead connector, and the '98 and newer 4Rs have a printed circuit internal harness with seperate bulkhead connector that uses less pins.  The TCC solenoid is different, but the EPC is as well, this is what keeps you from using the wrong internal harness.  You can stick a late model 4R into an older car, it wont burn the controller up, it just wont work.  That is why the Baumann site has 2 different conrollers.

On the subject of AOD to 4R swap, if you have the extra cash, do it, I cant wait to do it to mine!

I'm still on the fence on this. The AOD in the car is staying this year. I plan on doing the trans next spring. I have to decide if I really want to do the 4R70W or go with a built up AOD. I've found a shop that all the local 5.0 AOD Mustang guys go to. He's very good and builds a good product. It depends on my financial situation (ie if I have enough free money left over after bills, saving ect) as to what I'm going to go with. I'd love to go with a 4R70W but to get it done the way I want it (higher stall torque converter, VB mods) it will cost more than an AOD. But  I want my electronic trans lol.

Well, A good way to get an electric trans is to swap in a 4.6L+Trans, right? :burnout:

Why would I want a pos 4.6 (well except the dohc 4.6 from the 03-04 Cobra those are nice) when I've got a 5.0 HO? ;)

Hmmm for the simple fact that it is way more efficient per cubic inch at producing power than the 5.0 ever thought about being.  That is especially true if you get a 99+ 4.6 with the PI heads.  The only thing a 5.0 has going for it is that they are cheap as hell to work on and get parts for.

In the next few weeks I'll have a built AOD installed in my car (once my parts get here and my mechanic gets back from vacation) with all the goodies. And if you wanted a demo something could probably be arranged, our cars are pretty similar except for the fact that you have gt-40p's (stock heads for now:mad: ). Taking a spin in mine would give you a pretty good baseline for comparison.

Anyway there's plenty of time until next spring for you to make up your mind.
