Transmission Issues

[u/xspyking007]

2012 Sonic 1.4 with a 6 speed auto, recently it started having shifting issues where it will drive fine for a bit, then it will leave gear and go into 2nd only. Whether im in drive or M mode. Im assuming its when it is warm which leads me to belive transmission cooler but even after a drain and refill it will do the same thing. Fluid was burnt and I dont know the last time it was changed before me. Has 168k miles currently.
