I had a blown tranny in my 1996 that had TCU codes thrown but never a P1702 so I assumed the P1702 wasn't used to flag actual errors to the ECM.

I've only seen a P1702 thrown when the TCU harness is damaged, tranny is missing, or TCU is dead. But I learn new things every day.
I tend to agree. It is probably a blown cap. Where in NY are you? Maybe I can swing by and pick up your TCU, if you still have it. I will pay you for it if it works.
