Oh noo, the dreaded ford fluid change, sometimes its best to leave them pan and filters alone, seen this many many times, unfotunatley your gonna end up yanking the tranny to get a rebuild, its a goner now.

As far as your other problem goes> it sounds like you fuel level sending unit is bad in the fuel tank. That requires pulling the tank and R'R ing the fuel level sending unit assembly.
Goodluck, Cp
