Service Action S926
C20885-C62592
Issue:
The automatic transmissions on specific 2002 MY X-TYPE vehicles within the above
VIN range have the potential to contain a manufacturing flaw in the reverse clutch pack
that may lead to transmission slippage and ultimately, if the corrective action detailed in
this bulletin is not completed, transmission failure.
Vehicles with transmissions built in July and August 2001 are more likely to experience
this failure.
Action:
Identify and contact the drivers of those vehicles listed in this bulletin and arrange for
the vehicle to be brought into the workshop, at the driver’s earliest convenience, for the
transmission control module (TCM) to be re-flashed with the latest level of transmission
software.
Note: Only those specific vehicles listed in this bulletin require the
TCM re-flash under this Service Action.
The TCM re-flash is included on WDS release 19.
Make sure that the patch files provided on a separate CD-ROM have been
installed on the WDS.
