Hi Susie,
Refreshing that I am not the only person here with this problem.
I had my vehicle at different Ford service department this week. This will also be my fourth visit to service. Vehicle was kept for a week. Techs said they could not duplicate the problem. Stated on the ticket it was "normal operation" for this vehicle. According to the service manager they have had other 2019 Edges in for the same problem. He did contact Ford and was told the 2019 Edge 8F35 transmission is new. Has some type of adaptive learning system. ? I guess Ford is hoping the transmission will fix itself after learning your driving habits. Currently there are no service bulletins on the 2019 Edge 8F35 transmission.
To your question, I believe that TSB is for the Edge ST. The Edge Titanium has a different transmission, the 8F35. Not sure about your SEL.
I highly recommend you call Ford Customer Care at 800-392-3673 and open a case on your concern. They should be able to tell you which transmission is in your SEL.
