Hard down shift
2004 5.4l xlt 2wd has a hard downshift w/ heavy acceleration only in OD to 3rd.OD off heavy acceleration downshift is smooth to 2nd.Light acceleration downshift works fine in OD to 3rd. Is there a way for this year to reset the TCM to maybe fix this issue or is it something else. Thanks
