Maintenance Indicator - A/T: Description and Operation

CHANGE TRANS (TRANSMISSION) FLUID (AUTOMATIC TRANSMISSION)
This message indicates that the life of the transmission fluid has expired and it should be changed within 200 miles (320 km). See Scheduled Maintenance and Recommended Fluids and Lubricants for the proper fluid and change intervals.

When you reset the "Change Trans Fluid" message by clearing it from the display, you still must reset the transmission fluid life monitor separately.
