Pinpoint Tests

Power is routed through the transmission solenoid power control relay (inside the PCM ) to all transmission solenoids. If the power circuit to the transmission solenoids or the transmission solenoid power control relay fails open, all solenoids are failed electrically off. Check for open, short to ground or the transmission connector disconnected. The transmission solenoid power control relay disables power to the transmission solenoids when certain transmission Diagnostic Trouble Codes (DTCs) are set.

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).


Refer to Wiring Diagrams Cell 29 for schematic and connector information.

Shift Solenoid A (SSA)

Normal Operation and Fault Conditions

The PCM applies and releases the various clutches in the transmission by actuating the shift solenoids in the solenoid body. Shift Solenoid A (SSA) is a Variable Force Solenoid (VFS).

NOTE: Without a voltage signal return to the PCM , the transmission solenoid power control relay is commanded OFF. Using a fused jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that may be at fault, refer to DTC Charts for a fault listing.

Shift Solenoid D (SSD)

Normal Operation and Fault Conditions

The PCM applies and releases the various clutches in the transmission by actuating the shift solenoids in the solenoid body. Shift Solenoid D (SSD) is a Variable Force Solenoid (VFS).

NOTE: Without a voltage signal return to the PCM , the transmission solenoid power control relay is commanded OFF. Using a fused jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that may be at fault, refer to DTC Charts for a fault listing.

Transmission Solenoid Power Control

Normal Operation and Fault Conditions

The transmission solenoid power control relay controls vehicle power to all solenoids. Power is routed through the transmission solenoid power control relay (inside the PCM ) to all transmission solenoids. If the power circuit to the transmission solenoids or the transmission solenoid power control relay fails open, all solenoids are failed electrically off. Check for open, short to ground or the transmission connector disconnected. The transmission solenoid power control relay disables power to the transmission solenoids when certain transmission Diagnostic Trouble Codes (DTCs) are set.

NOTE: Without a voltage signal return to the PCM , the transmission solenoid power control relay is commanded OFF. Using a fused jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that may be at fault, refer to DTC Charts for a fault listing.

TFT Sensor

Normal Operation and Fault Conditions

The TFT sensor is located in the solenoid body leadframe. The resistance value of the TFT sensor varies with temperature change. The PCM monitors the voltage drop across the TFT sensor to determine the temperature of the transmission fluid. When the ignition is turned to the run position, the PCM uses this initial input signal to determine whether a cold start shift schedule is necessary. The cold start shift schedule allows delayed shifts when the transmission fluid is cold. The PCM inhibits TCC operation at low transmission fluid temperatures and adjusts line pressure to temperature.

Pressure Control Solenoid A (PCA)

Normal Operation and Fault Conditions

The PCM controls the hydraulic line pressure by varying the amount of current applied to the Pressure Control Solenoid A (PCA)/(Line Pressure Control (LPC)) solenoid. When no current is applied to the Pressure Control Solenoid A (PCA), the Pressure Control Solenoid A (PCA) is fully opened, resulting in the maximum amount of hydraulic pressure to the main pressure regulator valve. When maximum current is applied, the Pressure Control Solenoid A (PCA) is fully closed, resulting in minimum pressure to the main pressure regulator valve.

NOTE: Without a voltage signal return to the PCM , the transmission solenoid power control relay is commanded OFF. Using a fused jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that may be at fault, refer to DTC Charts for a fault listing.
