PINPOINT TEST A : Transmission Control Solenoids: Notes

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation 

Refer to Transmission Controls - 6R80 for schematic and connector information.

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.
