Some vehicles may experience excessive shift shock or a long time lag when shifting from p to r or from n to r. This is caused by miss learning of the tcm for shift timing. To correct the problem, the learning logic of the tcm has been changed.
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.
