Hi Clint. Did you check the maintenance schedule in your owner's manual?
Yes owner's manual say 60k my car have only 29k I was told to do every 30k because it gets dark quick and I don't know if the car came with reguler or synthetic ATF fluid from the factory what the best mileage to keep my transmission healthy thanks.
60k is pretty normal. I would stick to the manual recommended interval and fluid type.
