2014 Subaru A/T Oil Pressure light

Hey yall, I have a 2014 Subaru Impreza it’s at about 170K, at random like 3 months ago the A/T Oil Pressure sensor light came on (flashing) it killed off my ABS, and towing features. Car drives fine trans is not jerking at all, the light goes off, didn’t come back on till today. I’m not sure what to make of it. Help
