Update - tried adjusting linkage yesterday and no change.
I had ordered a new neutral safety switch anyway, replaced it today, and didn't make a difference, although I am glad I changed it as the seals on the switch that was in there were shot and it was dripping tranny fluid.

I made a 2nd attempt at adjusting the linkage and so far so good ! Have started it about a half a dozen times or so in Park ( and in neutral), won't start in other gears, car shifts good and indicators line up correctly on shifter.
Guess I just had to find the sweet spot. I marked it as well in case it happens again.

Thanks for the help!
