Hi, yesterday when running errands and on my way back home, my car would not drive in drive. I have a 2016 elantra with 100,000 miles or so. In July of this year I got a transmission flush at my local hyundai dealership. 2 codes show up p0722 and p0733, no engine light is on. It will drive in reverse but not in drive it revs up high but no movement. I keep up with matinetance and tire changes. Im really lost on what to do, please HELP!!!!!
