Pinpoint Test A : Transmission Control Solenoids: Notes

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Wiring Diagrams for schematic and connector information.
Normal Operation and Fault Conditions 
If the power circuit to the transmission solenoids fails open, then all solenoids are failed electrically off. Check for an open, short to ground or the transmission connector disconnected. The 10R80 utilizes 6 shift (A through F) solenoids that are linear force solenoids. Unlike previous shift solenoids they are mechanical in nature meaning no transmission fluid passes through them. CIDASs use an armature pin assembly that moves a control valve in the main control valve body to control and apply hydraulic fluid pressure. Each clutch (A through F) has a corresponding shift solenoid (A through F) that is directly proportional in that zero current equals zero pressure and maximum current equals maximum pressure. Since there is no pressure with zero current, none of the clutch packs are able to engage if the power is interrupted to the shift solenoids.
DTC Fault Trigger Conditions 
DTC Description Fault Trigger Condition
TCM P0657:00 Actuator Supply Voltage "A" Circuit/Open: No Sub Type Information This DTC sets if the TCM detects an open or short to ground in the TSPC circuitry.
TCM P0753:00 Shift Solenoid "A" Electrical: No Sub Type Information This DTC sets if the fault was not present long enough for the TCM to determine a more specific fault. If a more specific DTCs such as P0973, P0974 or P097A are set resolve them first.
