aggressively or driving on long hills can cause the
transmission fluid temperature to be higher than normal.
If this message appears, you may continue to drive at
a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230°F (1 10°C). The transmission fluid temperature
