Re: AOD transmission information ?
They're talking about the E4 number, indicating 1984 design code. F4 would be 1994. I don't have my decoder ring on, but PKA is the code for an AOD. I think it's PKC for an AOD-E. Anyway, newer than the E0 or E2 series is good, and something tells me the -DA was 5.0 Thunderbird, but I don't remember well enough to guarantee that. Without my references, I can only give one clue about what it was in - if you pull the overdrive servo piston, A was used with 5.0L HO, B was 5.0L, and C was 3.8L V6. Also, the tailshaft housing casting was E-something for cars, and the shorter truck casting was F-something.
Kultulz may have his reference, or I could hunt for mine, but the AOD isn't my bag anymore. I'd just go straight for the 4R70W and an aftermarket controller. I only mention this, because building an AOD for serious street power will need a lot of expensive parts that can often cost more than using a much stronger 4R70W with a $150 shift kit and a $600 controller. I don't know what power you're looking to handle, but if it's over 350 or so, I would just go for the 4R.
Be aware, the 4R70W is just an upgrade of the AOD-E, and that's an upgrade of the AOD. However, the number an types of differences are many, and by '99, it could handle upwards of 500 hp in a street car with only the shift kit and magic box. Also consider though, with that $600 box, you can change your shifting from mild to wild with a knob. Same for when and how it locks-up, etc. Something you can't do with a non-E trans. Just throwing options out there, as you are looking at quite an investment in any direction.
