MN | Here's the code I wrote. I am NOT a programmer. I'm sure there are more efficient ways to do this, better, etc.
There are two toggles, one for for/rev, the other for locking the trans in a particular gear. There are 3 led's for for/neu/rev, and led's for gears 1-5.
If someone leaves the tractor in for or rev it just leaves the tractor in neutral and flashes all the led's.
It might be easier to paste it back into the arduino editor to read it.

Anybody here messing with Arduino stuff?
