I fixed the issue! I think. Temporarily? So I searched on YouTube to see if maybe someone else had the same issue. Apparently the ignition switch gets faulty at times which makes the speedometer go dead and stops the transmission from shifting? Weird but I shoulder shrugged it. All I had to do was jab the little black box on the ignition with a screwdriver a few times and that brought back the gauges to life. Rpm’s climb up normally. Took the farm truck for a drive and the truck can shift now! It shifts a little aggressively but we’ll see what happens. For now I’m going to see if I can find someone to help me take apart the switch and clean it or maybe get it replaced.
