Official summary
Due to a manufacturing change, the CX-90 transmission has undergone a transmission part design change when replacing the transmission assembly. The new/superseded design can be used in place of the old/original design as the coolant hose (D-Code 21-5LX) is no longer needed to be used.
Vehicles covered
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.
