Official summary
Service Bulletin - Under very specific driving conditions the customer may notice the 2-3 upshift is more pronounced (firmer) than the other shifts. The transmission is working properly and this does not indicate a problem. This is not a durability concern.
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.
