Pinpoint Test E : Shift Solenoid E (SSE): Notes
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
Shift Solenoid E (SSE)
Refer to Transmission Controls - 6F50/6F55 for schematic and connector information.
Normal Operation
SSE controls the multiplexing of the SSD low/reverse and overdrive clutch. If SSE fails off (no pressure) then 1st gear is failed to 4th gear. If clutch select valve 2 sticks in the default position then 1st gear with engine braking is failed to 4th gear and reverse is failed to neutral. SSE is an On/Off solenoid.
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 Chart: PCM for a fault listing.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0770 | Shift Solenoid "E" | Open, short to power or short to ground in the solenoid or wire harness. |
| P0773 | Shift Solenoid "E" Electrical | Open or short to ground in the solenoid or wire harness. |
| P0774 | Shift Solenoid "E" Intermittent | Intermittent circuit in the solenoid or wire harness open, shorted to ground or shorted to power. |
