#07-07-30-006: Information on Control Solenoid Valve and Transmisison Control Solenoid Module Assembly Cleaning Procedure for Various Six-Speed HYDRA-MATIC Automatic Transmissions when MIL/DTCs Set - (Mar 27, 2007)
SI diagnostics for many of the performance DTCs that can be set by these transmissions direct that control solenoid valve and transmission control solenoid module assembly cleaning should be performed as part of circuit/system testing.
Perform the Control Solenoid Valve and Transmission Control Module Assembly Cleaning in an attempt to clean or free up a potential sticking valve of dirt or debris for the following DTCs :
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 should be run again to see if the DTC concern has been corrected.

Some customers may comment on a transmission concern where the MIL is illuminated and any of the above listed DTCs may be found in the TCM as active or history codes. They may also comment on harsh TCC engagement and debris may be found in the transmission oil pan.
If diagnosis leads to transmission removal inspect the torque converter face for signs of a high temperature witness mark as shown in the photo below. This witness mark will continue 360 degrees around the face of the converter and be blue / black in color.

I don't think this addresses the retaining ring problem. If I missed something please let me know.
I am sorry but I cannot find anything close to those trouble codes or doc ID number (when that doc ID number is XXXXX in it says either discontinued or not valid).
