Check automatic transmission fluid

you will want to have shop drain and refill because it is sealed unit and requires special pump to refill. To check it though, remove splash shield under engine, remove 3 bolts at bottom of front bumper cover. Unlock splash shield mounting bolts. Remove splash shield then use a 6 mm allen wrench to remove the fill/level check plug on tranny. Some fluid will leak out if the tranny is full.
