The control solenoid (w/ body and TCM) valve assembly cleaning procedure is a specific software based routine, which resides in the TCM. This procedure is activated by the scan tool and is used to cycle the solenoids and valves in the control solenoid valve assembly in an attempt to dislodge debris and free up the valves after a performance diagnostic trouble code (DTC) has set. When the cleaning procedure is completed, the DTC enable criteria is run again, and retested to see if the DTC concern has been corrected.

Important: The fluid pan must be removed in order to drain the fluid.

1. Operate the transmission to achieve 70-90°C (158-194°F).
2. With a scan tool, select the Service Cleaning Procedure. Initiate the cleaning procedure.
3. When the cleaning procedure is completed, turn OFF the ignition for 30 seconds.
4. Restart the engine and operate the vehicle according to the Conditions for Running the DTC
5. Observe whether the appropriate DTC run and pass in order to identify the Cleaning Procedure is valid.
