You could always take the plunge & replace the PCM.

It's not that expensive; $320.00 or so,

That's probably where I am heading.

I just had a feeling that the master reset was to easy! It was good for a while but then the errors started stacking up again. So Monday I bit the bullet and ordered a new PCM! It is supposed to be delivered Thursday. Hopefully that will be the end of this story!

New PCM installed. First test drive looked good. I will keep you posted.

That's what I wanted to hear.

Well, it was just too easy! And too good to be true!! Replacing the PCM was very easy.
It has gone back to old habits. No quite as often, but still getting errors. Most of the errors seem to point toward the TCM (P0700) now.
On my Commander the TCM is supposed to be a separate module. Can anyone tell me where it is located?

@BrerFox ;

I'm sure I can, let me do a little digging.

@BrerFox ;

The TCM is located under the steering column on the 3.7L V-6 XK.
