Hi, my John Deere 310G with VIN T0310GX919490 is experiencing issues. It does not turn forward or backward, the oil level is correct in the transmission, the hydraulic pump that moves the front and rear bucket works, can you help me by telling me what points to check and what transmission oil pressures to verify and their values. Thank you Carlos
Check the clutch cutout circuit first. That would be the buttons on the loader and shift levers. Voltage must pass through them to the neutral solenoid. If one is stuck or a wire for that circuit is broken, then the transmission will be put into neutral. Next, I would be checking the FNR lever itself.
