I have a 2006 NH TN75DA. The transmission will engage and go

Customer Question

I have a 2006 NH TN75DA. The transmission will engage and go in reverse but will not go forward. I have also had to wiggle the shuttle switch in order to start the tractor for the last year or so. I'm assuming the shuttle switch is bad
JA: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.
Customer: Any insight on remove and replace the shuttle switch?
JA: Anything else you want the agriculture mechanic to know before I connect you?
Customer: That's it now Thanks

Yes it sounds like the Shuttle lever OR the wiring connection.

Take the screws out of the 2 halves of the steering column cover. Remove the bottom half. This will allow you to access the connection. unplug and re plug a few times , then try start the tractor.

If the tractor starts this may ahve been the problem.
