Aerostar transmission question
What year was the last for non electronic control of the transmissions in Aerostars?
I'm asking bcause I want to put a SHO V6 into a Fox Mustang and I really don't want to deal with the electronic transmission controls.
Or maybe someone knows if the electronic controls interface and strategies are the same between Aerostar electronic autos and SHO autos?

The strategies are the same, and the transmissions can be tuned to the engines. It is a combination of using an adjustable modulator and adjusting the kickdown cable. The modulator is easy, there is a straightforward adjustment that is fairly true. With the kickdown, it has to be adjusted to the engines powerband. That is a bit more trial and error.

The A4LD through '88 has a single solenoid in the trans, grounded (activated) by the ECM. You can replace that with a switch. I can't recall whether that solenoid controls OD or TC lockup.
In '89, the A4LD went to two solenoids: one for OD enable, one for TC lockup. Both under ECM control. Again, you can use manual switches for these functions.
In '95, the A4LD went much more computerized. I am not familiar with the details.

In '95 the A4LD became the 4E44E. The computer now controls the 1-2 shift, the 2-3 shift, in other words, the shift points were no longer controlled by hydraulic pressure and internal governors, but rather the shifts occured on command from the computer. So '94 would be the last year you would want for your application. However, with the right circuitry, it is possible to make the 4E44E behave like a manual trans. In fact, you can engage OD on top of each gear, so you could actually make a 4E44E behave like a six speed, though I am not sure how well it would handle that.

Bear River,
That is true if you have a late model '95. My van is an early model '95. It still has OBD-I and an A4LD with a modulator. But you are right. To be on the safe side, he should look for a '94 or older.

thanks!
You guys are good. 
If I can use the latest ones it opens up the availability a lot.
Where would I get an adjustable modulator for the later trannys?
