Shift Solenoid Pre-Diagnosis
WARNING: This page is about a different car, the 2006 Mercury Milan and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Use the shift solenoid operation chart when carrying out PINPOINT TEST A: SHIFT AND TORQUE CONVERTER CLUTCH SOLENOIDS (ONLY) .
SOLENOID OPERATION CHART - CONVERTER ENGAGED
| Base Gearshift Selector Position | TCM Commanded D Gear | Main Valve Body | 5th Gear Valve Body | ||||
|---|---|---|---|---|---|---|---|
| Shift Solenoid SSPCA (PWM) | Shift Solenoid SSPCB (PWM) | Shift Solenoid SSPCC (PWM) | Shift Solenoid D (on/off) | Shift Solenoid E (on/off) | Shift Solenoid F (on/off) | ||
| D | 3 | On | Off | Off | Off | On | On |
| 4 | On | Off | Off | On | On | On | |
| 5 | On | Off | Off | On | On | Off | |
With a on/off solenoid, OFF = No Hydraulic Flow.
With a PWM solenoid, OFF = Full Hydraulic Flow.
PCA and PCB PWM solenoid percentage varies through all gears.
