This diagnostic trouble code is generated when the PTA control software detects that the transmission input speed is too high. It indicates excessive speed, particularly when there is no weight pushing from behind to justify it. This may be a sign of a fault in the speed sensor or the control software.

This diagnostic trouble code is generated when the PTA control software detects that the transmission oil filter is restricted. The pressure switch of the transmission oil filter opens when the transmission oil temperature exceeds 40°C (104°F), indicating a potential restriction in the filter.
- John Deere error PL4 codes
This error code is generated when there is a data transfer problem between the PL4 control software and the PL3 control software. The reception of messages sent on the CAN Bus by the PL3 control software is intermittent or non-existent. This typically indicates an open circuit in the CAN Bus, a short circuit, or faulty…
