Hello all, 2012 Hyundai Genesis 3.8L 93,8XX miles. I recently purchased the vehicle. I don't think it has ever had transmission fluid service done on it (still trying to verify). I'm wondering, with the mileage of the vehicle, if it would be safe to do a flush or should I stick with a drain and fill. I've heard that doing a flush at higher mileages can lead to the transmission misbehaving. Thanks. Daniel.
