Transmission Fluid Pressure Switch Test Procedure

  1. Remove the DT-47825  test block from the Q8 control solenoid valve assembly.
  2. With the Vehicle in Service Mode and the scan tool communicating with the vehicle, using a soft blunt object, depress each transmission fluid pressure switch port. The corresponding transmission fluid pressure switch parameter on the scan tool display should display HI when depressed and Low when released.
    • If the Q8 control solenoid valve assembly fails any of the above tests 

      Replace the Q8 Control Solenoid Valve Assembly.

    • If the Q8 control solenoid valve assembly passes the above tests 

      The concern is internal to the transmission.

  3. Repair as necessary.
