Even the adjustable stops won't help in this case, as the stops are only for 1st, 2nd, 3rd and 4th. the reverse can only be set via the neutral gate, it's a question of alignment. I've got mine too easy to slide in to reverse at this point, I'd like to narrow it down and make it harder, but getting out I'd like to go smooth.
Sometimes not much required to remedy, 1/2 turn either way.
