Pinpoint Test A : Shift Solenoid A (SSA): Notes

WARNING: This page is about a different car, the 2015 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

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 DTCs are set.

Carry out KOEO and KOER procedures.
Retrieve and record all DTCs.
Repair all non-transmission DTCs first.
Repair all transmission DTCs second.
Clear all continuous codes and attempt to repeat them.
Repair all continuous codes.
If only pass codes are obtained, REFER to: Diagnosis By Symptom . for further information and diagnosis.

Refer to Transmission Controls - 6F35 for schematic and connector information.

Normal Operation

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.
P0772	Shift Solenoid "E" Stuck On	This DTC means either: SSE short to ground, failed on (pressure). The clutch control bypass valve (multiplex valve) stuck in spring compressed position.
P0973	Shift Solenoid "A" Control Circuit Low	Short to ground in the solenoid or wire harness.
P0974	Shift Solenoid "A" Control Circuit High	Open circuit or short to power in the solenoid or wire harness.
