You can use the AOD shifter and cable, but any 94-97 t-bird and 93-95 mark VIII shifter will also work - and fit below the AOD consol just fine. 96-98 mark use a different style shifter that won't work.
The advantage of having the 4R70W shifter is that is has a built in "O/D off" button, and the proper PRND21 read-outs. You can program the PCS to use a toggle or momentary switch (like the factory O/D off switch).
After that video was taken, I had a guy on TCCoA (forget his name) make me custom gauge displays to replace the factory indicator lights (check engine, door ajar, etc) I had him add "O/D off", and "PERF. SHIFT", and "MANUAL MODE" in some blank areas that weren't used, then I powered them directly from the +12v programmable outputs on the PCS using led's. Looked like a factory fit and finish.
You'll also need a 94-97 T-bird/Cougar shift lever if you are using a mustang trans. 93-95 mark VIII works too, but the 96-97 mark viii's I saw looked like they used a mustang shift lever. Alan will know what you need in that regard.
You'll also need a 94-97 3.8L bird/cougar trans crossmember. The AOD one, or a 4.6L one won't work, you'll also need a 3.8L 94-97 cougar/bird driveshaft.. The v8 cars won't work, and the AOD/M5R2 driveshafts won't work either.
