Trouble Codes

[rgore1231]

Please help! I am not sure which way to go with this. I have a 2000 Expedition, 5.4, 4R100, 4x4. I was driving along and OD light starts flashing and transmission would no longer shift. I get it home and check the codes. There was a multitude of mostly transmission related ones. With over 215,00 miles on transmission and just over 80,000 on a newly replaced engine I decided to order a rebuild kit for the transmission. 2 weeks later, transmission back in the vehicle and I am pulling the same codes with no shifting. The codes are PO743, PO443, PO135, PO155, PO755, P1747, P1451, P1409. I removed and tested the transmission wiring harness and it checks out good. Any suggestions would be greatly appreciated.

Most of the codes went away when I replaced a blown fuse. This was most likely caused by a burnt wire on the exhaust manifold. One code left PO708. I will be replacing that part tomorrow.
