Circuit/System Verification

  1. Perform the TRANSMISSION FLUID CHECK  to verify correct fluid level and condition. The transmission fluid level should be within the crosshatch band and the transmission fluid should be red or dark brown.
  2. Perform the CONTROL SOLENOID VALVE AND TRANSMISSION CONTROL MODULE ASSEMBLY CLEANING  to dislodge debris and free up the valves.
  3. Operate the vehicle in drive with the calculated throttle position greater than 8 percent and ensure the TCC is commanded ON and OFF a minimum of 5 times. The DTCs should not set.
    • If a DTC sets, inspect the lower control valve body for a stuck clutch select valve 2, a broken clutch select valve 2 spring, debris or damage and repair or replace as necessary.
  4. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
