2010 Ford Fusion SE FWD 163k Miles

Have had this car for about 4 months now, about a week ago the wrench light came on and then turned off again after restarting the car. Today on my way to work I had to accelerate a lil faster than i normally do, however the car started to hesitate/stutter when getting higher in the RPM band. My service advancetrac warning light is on due to a failed wheel speed sensor which i have already ordered. I also need an o2 sensor for bank 1 sensor 2. Could either of those be the issue? I plan on taking it in for a Trans flush since I dont think the vehicle has ever has one done according to the carfax when i bought it.
