Official summary

Some vehicles may exhibit a chirp noise (stick-slip noise) from the automatic transaxle (AT) when shifting from 3 to 4 while driving. This may be caused by the automatic transaxle fluid (ATF) being contaminated by iron powder due to excessive wearing of the lock up clutch in the torque converter.

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.
