Official summary
Some 2013-2016 Fusion, MKZ and C-MAX vehicles equipped with an HF35 transmission and built on or before 15-Aug-2015 may exhibit a thumping/rubbing or grinding noise coming from the transmission. The noise may be present in all gear ranges including neutral when the vehicle is moving but will not be present when the vehicle is stationary or in park. This may be due to the differential side bearings and/or the transfer shaft and housing. To correct the condition, follow the Service Procedure to install either a transfer shaft kit or a remanufactured transmission assembly.

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.
