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.

Carry out KOEO and KOER procedures.
Retrieve and record all Diagnostic Trouble Codes (DTCs).
Repair all non-transmission Diagnostic Trouble Codes (DTCs) first.
Repair all transmission Diagnostic Trouble Codes (DTCs) second.
Clear all Continuous Memory Diagnostic Trouble Codes (CMDTCs) and attempt to repeat them.
Repair all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
If only pass codes are obtained,
REFER to: Diagnosis By Symptom (307-01 Automatic Transmission - Vehicles With: 6-Speed Automatic Transmission - 6F35, Diagnosis and Testing).

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.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
P0750	Shift Solenoid "A"	Open circuit in the solenoid or wire harness.
P0753	Shift Solenoid "A" Electrical	Open circuit in the solenoid or wire harness.
P0754	Shift Solenoid "A" Intermittent	Intermittent circuit in the solenoid or wire harness open, shorted to ground or shorted to power.

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.

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.

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 40 for schematic and connector information.

Transmission Fluid Pump

Normal Operation and Fault Conditions

The electronic transmission fluid auxiliary pump is used to keep the transmission engaged when the engine is stopped and the transmission is in drive. The electronic transmission fluid auxiliary pump has an internal microprocesser and communicates with the PCM over a PWM circuit with a frequency of 150 Hz with a duty cycle range of 10% to 90%.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
P0C27	Electric Transmission Fluid Pump Motor Current Low	This DTC sets if the E-pump communication is ok. The frequency is between 130 Hz and 170 Hz but a low current is detected (10% to 15% duty cycle).
P0C28	Electric Transmission Fluid Pump Motor Current High	This DTC sets if the E-pump communication is ok. The frequency is between 130 Hz and 170 Hz but a low current is detected (20% to 25% duty cycle).
P0C2C	Electric Transmission Fluid Pump Control Module Feedback Signal Range/Performance	This DTC sets if the E-pump communication is ok. The frequency is between 130 Hz and 170 Hz but the duty cycle does not match one of the defined duty cycle ranges.
P0C2D	Electric Transmission Fluid Pump Control Module Feedback Signal Low	This DTC sets if the duty cycle is less than 10%.
P0C2E	Electric Transmission Fluid Pump Control Module Feedback Signal High	This DTC sets if the duty cycle is greater than 90%.
P175A	Transmission Fluid Over Temperature Condition - Electric Transmission Fluid Pump Disabled	This DTC sets if the E-pump communication is ok. The frequency is between 130 Hz and 170 Hz but an over temperature condition is detected (30% to 34% duty cycle).
P2796	Electric Transmission Fluid Pump Control Circuit	This DTC sets when the E-pump is not receiving a signal on it's PWM input signal from the PCM .
