  1. Remove the DT 47825-1 from the control solenoid valve assembly.
  2. With the ignition ON and the scan tool communicating with the vehicle, using a soft blunt object such as the eraser end of a pencil, depress each transmission fluid pressure switch port. The corresponding TFP Switch parameter on the scan tool display should display HI when depressed and Low when released.
    • If the control solenoid valve assembly fails any of the above tests, replace the control solenoid valve assembly.
    • If the control solenoid valve assembly passes the above tests, the concern is internal to the transmission.
