good for 120K miles it's synthetic fluid, but that is a stretch if ya ask me i will be flushing mine with new strainer at dealership at 50K. kinda like my iridium Spark plugs they will not make it that far either, i am too pro active and i guess i have too much money!

how many miles ya got on it and how much towing have ya done? would not hurt to check level in it but be advised when ya do this ya gotta add about 1/2 qt back in it due to procedure!! explore link and pay attention closely to procedure and it is not that hard unless you make it hard.
