2002 Ford Taurus

I'm working on a 2002 Ford Taurus that's getting a number of codes. There are some oxygen sensor codes separate from these, and the following transmission control codes that I'm hoping I can find a root cause instead of writing off the entire transmission. The car has been sitting for a little while and seems to have no power when I drive it around a little, although admittedly I haven't been able to get it onto the road yet.

p0750, p0743, p0755, p0760, and p1747. (P1747 is an Electronic control short circuit.)

I wont bother listing the oxygen sensor codes, but if anyone could offer suggestions if this could be caused by one problem, or am I looking at a write off transmission?

If the tranny was operating properly before the vehicle was stored, it seems highly improbable that all shift solenoids would tank at the same time.

Check the wiring harness and circuits for voltage, ground, shorts, opens, etc.

Perhaps mice or other varmints have gnawed the wiring.
