Harsh bump feel during a 2-1 downshift.

Is 21-003-14 REV. A the most current TSB to correct the harsh bump feel during a 2-1 downshift? I'm definitely feeling this while crawling to a stop. Thanks.

Did a bit more searching and it appears there is a superseded version which includes the fix to retain ECO mode setting 21-004-15.

21-004-15 i believe is the latest and greatest. dealer applied it 2wks on my service visit. have noticed shifting is smoother.
