o2 ?

I have a 2003 f150 5.4 4x4 with a whole mess of codes P0443 p1451 p1747 p0755 p0743 p0135 p0155 p0403 i was driving the truck and it just bassically went in to N so to get home i had to manually shift it but it would only use 1 and 2 gear and the shift were very hard. I looked under the truck and found a harness for an o2 sensor melted on the exhaust. i have a new one on the way but would that cause all my other problems any info would be great because this is my only transportation besides my harley and its looking like rain for the rest of the week and riding in the rain get old fast

The condition blew a fuse.
The fuse feeds a lot of functions and caused all the codes including the transmission malfunctions.
Insulate the OX sensor harness and be sure it is clear and not grounded or crossed.
Replace the fuse to be able to use the truck again but you will still have OX sensor codes until they are hooked up and working again.
You may even have codes telling you one or both banks are too rich without the OX sensor working.
The rest should clear and trans should shift of again unless you missed something.
The harness is about $115 +/-.
Dealer needs the number off the harness tag to order the correct replacement.
Good luck.
