Answer 1

P0757 Mechanical or hydraulic failure of the shift solenoid (SSE)

You may still have to do a transmission service, just to inspect the fluid condition if heavy sediment caused the solenoid to stay open. Ford uses the smart junction fuse box.When one fuse open it set off a variety of component to act up. The first is to inspect for open fuse , the SSE in question is natuarally in a open position unless given the command from the ECM which then go into a closed position , So there may not even be a connection to this solenoid SSE. In the fuse junction box Fuse # 26 ,fuse 23 and fuse 26. A short to ground can have cause this condition
