Do having circuit fault in the B clutch actuator or circuit deal with gears

Yes, the "B" clutch is part of the internal automatic transmission. It would seem to me that it's related to your concern if you're sharing that information. You might be covered by some kind of additional warranty coverage on your transmission through Ford; check with your local dealership -- there were some issues with the dual clutch automatic transmissions if yours is so equipped. Worth checking into.
