good morning. I have a problem with my lt77 suffix G gearbox. For a few months when I put it in reverse if I didn't hold the gear lever with my hand the gear would pop out banging like tok tok. For a couple of days I put it in reverse but the reverse gear won't engage. Do you have any advice before I disassemble and overhaul the entire gearbox. Thanks. A big hello to all lovers of these tractors.
