Yes.
You can screw the switch out for a test to see if it is causing interference. You should be able to back it out with out a lot of force.
The best position is where the switch just engages (switches) reliably in reverse.
Good luck.
Can you overlay the two plates? It is suspicious if the problem started when you changed plates.
If you are thinking about adjusting the linkage at the turnbuckle forward of the trunnions bushing, make sure you fix the shift lever in the canter of the gate with wooden wedges before you mess with the adjustment.
Much easier.
