First thing, disconnect the batteries overnight to clear the codes and reset the computer. Let's start with a clean slate.
One thing that I can think of that would put the trans into limp mode (high, hard shifts) is Torque Converter Clutch slippage. It has a code, forget what it is.
Wal-Mart had Ford code readers for about $35, you might want to pick one up to pull codes if they recur after resetting the computer.
