Pinpoint Test A: Shift Solenoids

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to Wiring Diagrams TRANSMISSION CONTROLS - 10R80 for schematic and connector information.

    Normal Operation and Fault Conditions 

    The 10R80 transmission uses 6 linear force shift solenoids (A, B, C, D, E, F) called Casting Integrated Direct Acting Solenoids (CIDAS). Unlike previous shift solenoids, they are mechanical in nature meaning no transmission fluid passes through them. They 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, B, C, D, E, F) has a corresponding shift solenoid (A, B, C, D, E, 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.
