If the 3000 plugged in, it should work. Maybe You have a pin that got out of alignment. Be sure to calibrate the TCM when ou put the receiver on. That will mess with ability to run straight.
The clunking inside may be the harness. Take the 3 big phillips screws out of the bottom, and remove the mount from the globe. Unplug the globe and then shake it and see if it still clunks. It shouldn't. If still clunks, take it to Your JD dealer, or AgExpress for repair.
If it is quiet there was probably just a bit of the harness bouncing in there.
