Jay,
It was the switch. I changed it out this AM. Thanks.
Amazing what this switch affects.
Shifts were harsh, both up and down. Cruise didn't work. Couldn't get TC lock-up. As a result, my gas mileage dropped significantly. As it turned out, the park lock worked, and I had reverse and four auto-gears forward, but the tranny did not respond to the manual switch, or to selection of 1, 2, or 3. Any of those was equivalent to having it in drive.
On a positive note - DID have forward and reverse, so I was never stranded
