****ft sticks in park occasionally

I have a 1993 Nissan Automatic transmission

****ft sticks in park occasionally.

I have determined it is not the solenoid

I do not think it is the backup/neutral safety switch-still starts in
park & neutral.

Ever time  I take it to my mechanic,  it does not stick.

It even sticks,  when the car is in aux and your are trying to ****ft
it to neutral to start the car.

Even through the solenoid,  something is occasionally  not telling the
****fter that it is ok to ****ft.

Any bypass tricks to force it to ****ft, when this happen?

Would bad or worn brake pads cause this?

No, I am not having any breaking problems yet.
