Shift Solenoid Pre-Diagnosis
WARNING: This page is about a different car, the 2009 Mercury Milan and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Use the following solenoid operation chart when carrying out Pinpoint Test A.
SOLENOID OPERATION CHART - CONVERTER ENGAGED
| Selector Lever Position | TCM Commanded D Gear | Main Valve Body | 5th Gear Valve Body | ||||
|---|---|---|---|---|---|---|---|
| SSPCA PWM | SSPCB PWM | SSPCC PWM | SSD (ON/OFF) | SSE (ON/OFF) | SSF (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 Pulse-Width Modulation (PWM) solenoid, OFF = Full Hydraulic Flow. Pressure Control Solenoid A (PCA) and Pressure Control Solenoid B (PCB) PWM solenoid percentage varies through all gears. |
