Okay,

So after some GREAT advice from Jerry (he IS the MAN!!!), I found that the tranny doesnt appear to be suffering mechanically, but is ailing electronically.

He had me remove the trans selector plug, forward of the shifter linkage on the tranny.

I did this and was able to manually shift through the gears. Once I plugged it back in, I was stuck in the same situation as before with 1st and 2nd only.

What is this limp mode you speak of, and how do I reboot the TCM/ECM? I tried the unplugging of the battery and that didnt help. Clearing of codes stored, like at Auto Zone?

Thanks guys.
