    • Measure the 9VFS solenoid’s electrical signal for abnormalities.

  4. Solenoid or TCM Repair / Programming

    • Replace or repair faulty solenoids.

    • Reprogram TCM if required.

  5. Transmission Adaptation Reset

    • Reset adaptive values to restore proper shifting and hydraulic pressure.
