Just wondering what cd manual you ordered? The operations and test manual? Think we are going to have to order one because the one we just ordered didn't have the wiring diagrams we need for our 2000 6410. Tractor was running fine, but left hand reverser kicked into N and started beeping after 30 min of running so we've changed everything we know possible to try and fix it. Changed the pressure enable switch this past weekend and now the tractor won't move at all! Put the old switch back on and still nothing. Sounds electrical to me, but we are stumped!
