Official summary
Due to a manufacturing change, the CX-70/CX-90 transmission has undergone a transmission part design change when replacing the transmission assembly. Old design originally required a coolant line running to the top of the bell housing, the new design has omitted the hole and need for the coolant line. The new/superseded design can be used in place of the old/original design and the coolant hose is no longer needed to be used.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.
