07 Honda 420trx Rancher won’t shift

I have a 07 Honda 420trx rancher. We have replaced the electronic shift motor and the angle sensor. It will not shift at all. It doesn’t even try. Does not click or make any noise at all. What other options do I have? Can manually shift but hard to do. After replacing the shift motor and angle sensor it stopped throwing codes but still will not shift… any ideas on what to replace next or work on next?
