Hi Andy,
You may need a diagnostic scan to be sure.
Possibly just a wiring problem or possibly the gearbox has just come to the end of the road..
could be a variety of things but the best idea would be a scan first of all

I had a scan it said Vss but i haven't had the error codes removed or the PCM updated does this matter? The oil is fine and the gearbox its self is ok. As for the wiring i repaired and replaced what was damaged this took forever. If I do need a PCM update does anyone know anyone, who can do this in my area?

The smiley system conked out with the last site breakdown a few weeks ago !!
Have you changed your VSS ? whether or not you clear the codes out is of no great importance,that is until you have another problem and the old codes come up.Any small garage should have the equipment to read and exit codes

Andy, are you still getting somewhat correct speed readings, or does it drop to zero occasionally while driving?

Is it even after you changed VSS? How long does it stay at zero? You mentioned fixing some wiring, was it for the VSS you meant? If it's only the VSS, these gear shift problems should appear only when the speedo reading is zero or clearly wrong.
But VSS are wear items, they have a bearing, on mine it was shot causing resistance (-> heat) when trying to rotate it. I think that explained why it dropped to zero after some driving. It was fixed the second it was replaced. But then again, I put a brand new one in.

andyg66 - welcome to our great forum.
When it dropped out did you lose Cruise Control as well?
If not all symptoms point to the engine loom travelling over the engine towards the autobox. It connects with the main engine compartment loom with 2 square connectors next to the exhaust manifold.
I had my engine-autobox loom replaced years ago and that cured all erratic problems as racing enine, cut outs, etc.
The area next to the manifold is suspect as well because of intense heat when stationary; view my pics below of the blown main engine compartment loom.
http://picasaweb.google.nl/babpic123/Aegon?authkey=Gv1sRgCNmu4LaW36q0hAE &feat=directlink
In the larger drawing your suspect engine-autobox loom is number 5 and 14 . # 5 is highly suspect because of overhead engine-heat but I would certainly inspect and clean all related connectors.
HTH ,
Ray

If you have AVC (automatic volume control) on your radio & have set it up, the volume may fluctuate if the VSS is playing up.
If you've disconnected the battery since setting up AVC it may not still be set up.

... symptoms point to engine-autobox loom I am afraid...
It rusn over the top of the engine then down to the box. Please do inspect its quality.
The worst area is between the fuelrail and the injectors. Once you see brittle isolation of the strands anywhere then it is bad news I fear.

... that is a pity  ... what to do now?
Well - this particular separate engine-autobox loom in return is fed from the engine-compartment loom to the EEC. So all signals governing INJ and autobox have to pass through the latter.
It is well worth checking whether the infamous section of this engine-compartment loom, sitting next next to the red-hot exhaust manifold, rougly located between ABS-module and the EGR sensor on the chassisbeam, contains brittle wires and strands.
I will bet you it is. Look at my pics-link above and you will recognise this section.
It is wound in plastic/sometimes cottontape holding the strands toghether. Cut this open lenghtwise! oh so delicately with a small cutter.
Through this section anything governing your engine's performance and behaviour is transmitted, except 3 EGR sensor-strands.
Because of persistent heat and dampness it is Scorpio's weakest spot. I am having mine now replaced with a much younger one I found in Germany (LHD). It is 7 meters of loom from rear to front... with one bad section.
Hope I am wrong - but then what?
Ray

Not quite but - but the design follows the same rules and mistakes.
So use the diagrams but stay aware of the flaws.
