At what mileage should I change or flush the trasmission fluid. I get different answers at the dealer.

Depending on the make and model, it is recommended anywhere from 50,000 to 150,000 miles. Other variables include operating temperatures, and how hard the transmission is worked. In a normal passenger car, not used for towing, I would personally recommend changing it at 100,000. There is a lot of different views on this subject but consider the kind of use your transmission gets. Examples would be heavy loads or a lot of city stop and go driving.

Thanks Mark, your answer has been the best and made more sense than any of the answers the dealers themselves gave! Very much appreciated!! Its a 2011 Hyundai Sonata 2.0T. I use it in more city stop and go traffic daily. You know the everyday type traffic one takes to and from work. My baby does NOT do heavy loads. Thanks again for your help!
