Question about 2002 Lincoln LS
Yes for the wiring and computer causing shift problems and maybe for you fixing it yourself.
One thing you might do is give an exact detailed account of what shift problems you are having. As in upshift, downshift, or which gears it appears to have problems with. Also is the same problem occurring with either transmission?
One thing you need to remember is that many problems are suppose to be reported by your onboard computer. Your "check engine" light also includes transmission defects. To some extent bad wiring will result in either a "loss of signal" code or "out of range" codes.
Strange as it may seem, have your battery and entire charging system checked. Autozone, Advance, and Oreily usually check those items free. All of your performance settings are based on a good battery voltage and low power will mean some values can fall out of range and affect shifting.
You have a few options. A bad wiring loom can be obtained from a Salvage yard. Some computers have rewriteable memories which can be reprogrammed if some mental gaps have been created by prior shorting.
Probably the best thing to do after having the battery and charging system checked is to break down and take the car to a Dealer for a different kind of diagnostic testing machine to be hooked up.
This machine is actually installed in your car and the car is driven on the road. This machine goes way beyond most handheld scanners. It monitors more components and can be rigged to be placed in-between wiring connectors to measure problems before and after where it is attached.
The chassis pin connector may have 100 wires at the junction, so you can see that a machine which tests 100 wires at a time can quickly detect a problem you would need many hours and a diagram to locate manually.
I believe different manufacturers have their own name for this machine. One used to be called an "Odessey" or "Oasis" I believe.
As for corrosion, another question is with the 2 repairs, did it shift correctly for a short time? Because the end connections were removed from the transmission and may have temporarily made clean contacts when reconnected.
I hope I have been of some help on this.

Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.
