Any idea on where to start

I would start by checking all your wiring harness connections for broken or rusted pins in the connectors. Also check the harnesses for broken wires. If you have a second machine you can easily swap the shifters to make sure the issue isn’t in the shifter. You can also swap the harnesses around on the front and rear TCUs (under the cab) to and see if that changes your problem from the front to rear or vice versa. The wiring for the transmissions on these machines is a weak point. Get someone that is good at trouble shooting electrical issues to look at it and they can probably chase down the problem pretty quick. You may want to get parts and service manuals if you don’t already have them to assist with trouble shooting. I’m not a mechanic but I ran several of these years ago this was a common problem.

Questionable Wizard on here knows a lot about these machines so maybe he will chime in with some advice for you.

The wiring issues can seem a little overwhelming and complicated but don’t give up on it, they aren’t bad machines, just keep it maintained it will serve you well once you get this issue sorted out.
