Stop in for a cup of coffee

Transmission work...

Park cable adjusted and passes Park engagement test (roll in neutral, Park Off.....Park On, does not move).

Shift cable failed test. Assuming that if the :"Park" goes in and out of Park that the inability to obtain any gear may not be a cable issue but something more nefarious

I'll build an "assistant" tomorrow.and run through the shift cable adjustment

Changed the light switch and cleaned up the pushbuttons while I had. It all apart
