Book says transmission in gear when key was turned on. I cleared all codes and started the tractor again. It's in park the A pillar says it's in park but I still get the code. It won't go into gear. If I take it out of park the A pillar says neutral but if I go into forward or reverse it continues to say neutral and doesn't go into gear. What am I missing
John deere 8100 PCU 66 code
