Eaton Gen 1 (AutoShift) Fault Code: 57 PID: PID 160 FMI: 2 Main Shaft Speed Sensor

Overview:
This code indicates an electrical problem in the main shaft speed sensor circuit. The signal from the sensor did not match the current operating conditions.

Detection:
A Speed Sensor is determined faulty when all the Speed Sensor readings are compared and one sensor is inconsistent.

Fallback:
There is no fallback mode, because Main Shaft speed can be calculated from output shaft speed (may slow down shifting).

Required Tools:
1) Basic Hand Tools
2) Digital Volt/Ohm Meter
3) AutoSelect/AutoShift Troubleshooting Guide

Possible Causes:
1) Loose speed sensor
2) Contaminated sensor end
3) Damaged transmission harness
4) Malfunctioning main shaft speed sensor
5) Malfunctioning transmission ECU
