Official summary
This article supersedes TSB 23-2160 to update the parts list. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: * An illuminated powertrain malfunction (wrench) indicator with DTC P07F7 * Loss of 10th gear. The vehicle may also exhibit harsh engagements and poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit leaks.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
