Transmission Overview
Ford’s AODE was originally a fully hydraulic transmission, that Ford modified to full computer control. It uses two main solenoids to control shifting. These solenoids receive power whenever the key is on; the computer supplies ground to energize them. An EPC solenoid controls mainline pressure electronically.

Terminal Identification
Here’s a breakdown of the individual connector terminals:

Shown from the terminal side of the transmission connector.

Electronic Pressure Control
To check the electronic pressure control signal, connect your high-impedance voltmeter or signal monitor to the terminals shown.

Checking the Shift Pattern
Here’s how to connect your signal monitor to check the transmission shift signals:

And here's the signal pattern you should see:

Forcing the Shift
Here's the manual shift pattern you can expect with the transmission in failsafe:

And here's how to force the AODE to shift electrically:

First Gear
In first gear, only solenoid 1 receives ground.

Second Gear
To shift into second gear, the computer releases ground from solenoid 1; neither solenoid is grounded.

Third Gear
To shift into third gear, the computer grounds solenoid 2.

Fourth Gear
To shift into fourth gear, the computer grounds both shift solenoids.
