What exactly is the shift interrupter & what is it for? I did a search & couldn't really find an explanation. And does my '76 have one? It's a 140 3.0L #1(R) drive. Thanks.

It is not that common for the switch to go bad. Usually is it a lower shift cable that is bad.Thanks Eric, don't know how I missed that part of the sticky but that explains it well.
I assume if the switch goes bad & the shifter doesn't want to come out of gear, that one could & probably should just cut the engine off, then shift to neutral & restart the engine once you're in nuetral?

Bad idea. Problem with that process is when you have to shift out of gear in tight quarters...like docking of retrieving. Best to get it fixed right.
Not uncommon for someone to "fix" a bad shift cable by disconnecting the switch though.It is not that common for the switch to go bad. Usually is it a lower shift cable that is bad.
