Wrench Light!

Good morning! About 200 miles into a 500 mile road trip yesterday my wrench light came on in my 2017 Explorer with the 3.5 naturally aspirated engine. When it happened I was doing about 88 mph and did not notice any driveability issues. While exiting the highway to get fuel it felt like a slight misfire. Restarted the car after fueling and the light has not reappeared. I did notice one slight misfire late last night, but nothing else.

Unfortunately I didn't bring my OBDII dangle so I can't scan with forscan and Autozone couldn't pull any codes. Has anyone ever experienced this sort of thing? I did an oil change in it the day before and used Motorcraft oil and filter. I am wondering if maybe I justvgot some bad fuel to start the trip.

Thanks in advance for any help! I just want to give my wife peace of mind that we'll make it home lol.

Forscan had some codes for the transmission temperature sensor. I was able to diagnose and determined that the solenoid pack needed to help replaced. I replaced the part and programmed it through Forscan. So far no issues, but it has only been on site trips since then. I will be taking it over the road in a few weeks, so that will be the real test.
