Eaton Gen 1 (AutoShift) Fault Code: 43 PID: SID 35 FMI: 4 Range Solenoid Valve
Overview:
This code indicates an electrical failure of the solenoids that control the pneumatic range valve.
Detection:
Starting at key-on and throughout operation, the Transmission Controller constantly measures this circuit. A failure mode of short to battery, short to ground, or open circuit is detected.
Fallback:
This fault causes a 5-speed fallback and the transmission stays in either LO range or HI range. When the vehicle comes to a stop, an attempt to shift into LO range is made.
Required Tools:
1) Basic Hand Tools
2) Digital Volt/Ohm Meter
3) AutoSelect/AutoShift Troubleshooting Guide
Possible Causes:
1) Range solenoid coil open or shorted
2) Damaged transmission harness
3) Malfunctioning transmission ECU
